@Tabox HQ so I tried to re-install but that didn't work, however I think I found out what the problem is. I'm currently using the browser called 'naver whale', which is a chromium based browser, so it shares the chrome web extensions. I tested on the chrome browser and the login window popped up, so I guess this browser I'm using (whale) doesn't support the identity api scope approval ui..?

@Tabox HQ Hi, thanks for the quick reply! Well I tried that disable things but that didn't help, either. I don't think I've tried the re-installation. I'll do that and see if that works. Will reply again. Thank you!

Hi, I'm having the same problem here. the Sync button doesn't really work, I've checked the devTool and there's no button at all. I also tried to use it on the private window, with only the Tabox but no other extensions, and it's still not working! so I don't think it's because of the confliction between extensions. please please help me out, I really like to use Tabox, I need to sync my google id so I can use it on my other computer!
