Yeah, as Anshuman shared, you shouldn’t be affected by this issue - we’ve checked your account. It’s weird!

But thank you for sharing all that information, we shared it with our product team to take a look. They are based out in SF so there will be delays in responses, appreciate you being patience :slight_smile:
