There is a strange behaviour I noticed when I submitted AI Smart Assist app for review.
Here is a recording. App Loading Issue - YouTube
The app seems to render fine on Chrome. However, in Brave and Edge it does not proceed and seems to be stuck in app.initialized() forever.
I updated the Brave browser to the latest Chromium version 113.0 and the issue disappeared.
However, it still remains on Edge. There is also a customer support ticket that I received for the already published Version 1 of the app not working on Edge.
