Partner can approve booking from theme version 2.0.2.
1. I also get this effect that i have to wait about ~2s to change to other tab.
2. I have checked and see the card Accept image does not work.
You can check it in Traveler Setting > Booking Options > Accepted Cards then try to upload new image to check again.
3. We will release new theme version in a few hours later. Please wait to update then check again.
