PC Win 10. Sync Version v2.4.6.82. 1.5GB of 100GB used.
Syncing works for a while, then some days not sync anything. Makes it difficult to collaborate. I am waiting for another designers files to sync to my PC. I created the folder initially and invited them to 'Edit'. They can see all my updates, but I can't get theirs.

• Turned off syncing in Preferences.


• Closed Creative Cloud App.


• Opened Task Manager and 'End Process' for all CC Background processes, eg 'Creative Cloud (32 Bit)', 'Core Sync (32 Bit)', etc (about 6 of them).


• Re-opened Creative Cloud App.


• Turned on syncing in Preferences


• 'Syncing...' appears briefly at the bottom of the CC App.


• nothing changes.

Also tried:
- Permanently delete the 'Deleted' files via browser (Assets > Deleted)
- sign in/sign via CC App
- restart PC several times
- update all CC Apps (even though nothing to do with syncing)

Nothing is working, except waiting a few weeks and it might work then.

File locations get lost or the "version" of the InDesign or Illustrator that the file was created in is no longer available. Didn't have these issues before the last CC upgrade. Just yesterday, I saved an Illustrator file and know that I saved it. Then, did a save as to rename and make changes for a new version. The previous version vanished, an image in the recent listing menu appeared, but couldn't be found to open. Now vanished as if it never existed. Had to start my original file over using my now changed version. Just took the entire morning doing it again.

Sharing swatches using libraries is totally unreliable.

From InDesign:
I created a Green Spot Pantone color in InDesign: PANTONE 321 C and added it to a CC library
To an Illustrator document
In Illustrator I double clicked that swatch from the CC library and it was added to my Swatches panel as PANTONE 321 C, but it became a Global Process Color in CMYK mode as 100% Magenta.
A totally different color, it should have stayed a Book color, with Lab values and it should not have changed to Magenta.
To an InDesign document
Adding the same color from the CC Library to an InDesign document by double clicking shows the Colour Picker and allows you to Add Lab Swatch. The colour mode and lab values areright, but it becomes a Process color and the PANTONE 321 C name is lost.
Adding the same color in the CC Library to an InDesign document by Ctrl clicking in the Library and choosing Add to Swatches works as expected, it adds a Spot color with the correct name and Lab values.

From Illustrator
I created a Green Spot Pantone color in Illustrator: PANTONE 321 C and added it to a CC library
To an InDesign document
Adding the color in the CC Library to an InDesign document by double clicking shows the Colour Picker and allows you to Add CMYK Swatch. It becomes a Process color in CMYK mode, the lab values are different and the PANTONE 321 C name is lost.
Adding the same color in the CC Library to an InDesign document by Ctrl clicking in the Library and choosing Add to Swatches, adds the correct Pantone Name, keeps it as Spot, but changes the Colour Mode from Lab to CMYK.
To an Illustrator document
Adding the same color from the CC Library to an Illustrator document shows the Colour Picker and allows you to click OK. It adds the swatch to the Swatches panel, adds it as Spot and keeps the Pantone name, but loses the Lab values and Book Color Mode.
Adding the same color in the CC Library to an Illustrator document by Ctrl clicking in the Library and choosing Add to Swatches, adds them twice, loses the Pantone Name and they become a Spot colours in CMYK mode.

The only time it works as expected is when the Pantone swatch was created and used in InDesign and added to the swatches in a new InDesign document by Ctrl clicking from the CC Library.

All documents were in CMYK mode when swatches were added and used in CC Libraries.

I am not even touching the subject of Color Managed swatches in CC libraries.

I have had issues in the past with CC Desktop Sync not playing nicely when Google Drive is installed on my compooter. Either the file icons don't update properly with the green checkmarks or blue sync icons, or the system fails to sync at all.

Currently, I'm happy to report that all is working -- because I haven't had Google Drive on my laptop.

But I'd like to have both on my laptop. Before I try installing Google Drive Sync on my laptop again, I'm wondering if this issue has been resolved?

I don't want to be The Guinea Pig if I don't have to. ;-)
