I am having an problem adding a new form I created within a specific microsoft team. I click the + button to add "forms" it provides a pop up window where is says loading, then it loads a blank screen. The only two options I have are to press the "back" button or the "x" to exit out of the pop up window. Help? I see that there was an issue back in 2018 that was apparently resolved, but I am experiencing it now in 2019. Is it a permissions issue? Do I need to contact our admin?
I have just tested it in my tenant - both adding a new and existing form. No problem here. Also no problem on service status with Forms.
Sounds like it could be an issue with licencing - I would raise this to your admins and just to double check you are licenced with Forms. I would also ask them if Forms is included if an app permissions policy has been applied to your team.
Also, prior to raising with the admin I would check the issue is persistent in the web version (login to teams.microsoft.com and test) - if it is, it's a definite raise and could be one of the two issues above. If it works as expected this could be an issue with the desktop client and so try 1.) Logging out and back in and 2.) Clearing the cache (https://commsverse.blog/2018/09/28/clear-the-microsoft-teams-client-cache/) - again if none of these work raise to your admins.
If all else fails then your admins will open a ticket to Microsoft
