Trying to integrate anything other than circles backs to a minimized same screen

Hi Team,

Greetings for the day!

As you can see that in the below screenshot I had luck with only the calendar . If I try to integrate Slack, Gmail, Notion it opens up a minimized same screen after a quick white screen and when clicked plus icon inside this minimized screen again reverts to the maximized screen with all the same options a constant regressive loop.
