Shared Libraries access not functioning across team

[DaronWP]

Our team is now on day 7 of working with Adobe support on this issue and it still hasn't been resolved. So I'm turning to the forums to see if anyone here has any insight. 

I've created a new library of mogrts (created in AE). I created it under the "Everyone" setting, meaning everyone has access to it when they click the Browse All option. I can share it with individual team members using the "Invite people" option. Team members are able to see and accept the invitation. The library shows up in their web browser when they visit assets.adobe.com. The library does not show up in their creative cloud desktop app. It does not show up in the Libraries window in Premiere and After Effects. They are not able to see them in the libraries dropdown menu in the Premiere Essential Graphics panel. 

What are we missing here? Any insight is helpful as the Adobe customer care reps we've talked to are completely stumped. I'm posting this in Enterprise & Teams support since this is not a program-specific problem. It doesn't work in any application.

Thanks!

We actually think the problem might be VPN interference. When our users disconnected from our VPN they were able to sync the libraries. I think what tripped us up with this is that there was no error message in Creative Cloud that the files weren't syncing properly - everyone's sync said files were up to date. Unfortunately some of our users aren't able to disconnect from the VPN so we're still facing library sync issues. Wish us luck.
