Hi fg2001
I have exactly the same problem that you describe, in fact I raised a question on this forum about it.
Restarting the Function Discovery Resource Publication Service will fix the problem, until the next restart.
I've set up 3 shortcuts (\PC-A, \PC-B, \PC-C) in File Explorer\Quick Access, as a work around. You can also map the shared drives as an alternative.
Presumably Microsoft will come up with a fix in due course.
Hi TcatHF,
The shortcuts work too or you can use the workaround suggested by Plarini earlier on this thread to restart FDResPub with the task scheduler until Microsoft fixes the root of the bug.
