I'm interested, does Adobe downloads our fonts while synchronizing?
How do we check if it does? So, for example, if your ISP isn't working, you'll be unable to work? That sucks!
We’ve been able to identify one scenario in which the cache folder is not accessible while InDesign is launched, resulting in the issue. The issue seems to be specific to MAC OS.
We have released an update for InDesign CC2019 (v 14.0.2) which contains some stability fixes. If you are not already on 14.0.2, then we recommend you to update to latest version.
If you still encounter the issue again, try to access the location “/Users//Library/Caches/Adobe InDesign/Version/14.0/en_US/InDesign Recovery/*” and create a file in the directory.
Workaround – Quit & relaunch the application, Cache folder gets created and the problem is resolved.
Laugh through crying. Oh, Adobe, oh stop that madness!
It is Win7x64 v 13.1x64
