Hey there!
As we know that Antigravity is having alot of bugs related to Tokens and limits, so i tried logging out from the current account to other account of my friend who is also Pro user, when i try logging in using it , the browser isnt redirecting me to antigravity for successful login, also if explicitly clicked to open antigravity its not logging in , to debug i open Chrome’s Developer Options where under network screen i can see the error log for this particular account,
This account is new and not used before in any device also for antigravity so no mean that it may be banned!
Do resolve the issues ASAP
