Cannot ADD Provider/SharePoint hosted APP in SharePoint subscription edition

[Padmanaban_Jayaraman]

When we try to add APP (both Provider hosted and SharePoint hosted APP) in the site collection, the Grant Permission to an App dialog (Trust it dialog) greyed out and seeing the Connection close error. This issue happens only with SharePoint subscription Edition.  PFA screenshot.

Hi Mike Lee,

No Status not changes after I posted.
Here are the steps to reproduce the issue:
1) Create Web application.
2) Create a APP Catalog
3) Upload a hosted APP in APP Catalog.
4) Create a site collection
5) Try add APP in the site collection.
6) "Trust it" Dialog is greyed out

Let me know if more details required.
Thanks

Hello Padmanaban,

Unfortunately, this workaround for this issue will not make it into our Public Preview release. We are targetting the 2nd half of 2021 for the RTM release.
