Hi there Tabox! I am loving this program and it has been a lifesaver for someone who bounces around a lot of devices for work reasons.
I have lately been getting an error where I am unable to open the sync window on one of my devices. I will try to reinstall etc, but was wondering if you might know what it could be?
Sync feature has been working prior but stopped in the last two months, so I have been exporting out the sites.

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!
Thanks @Phil Merricks ! I will instruct other users reporting this issue to check for any security extensions that might interfere!
Solved, apparently the Bitwarden extension messes with OAuth windows. I disabled that temporarily and it all works again.
I'm seeing the same thing here, but only in the Vivaldi Browser. Edge works just fine. I am bugging Vivaldi also :)
Thanks for reporting, Trygve! I don’t see the issue myself but I will continue to look into it!
Looks like a "turn-off and on again" approach was needed. It is working now but I will leave it up for others to see.
