Thank you very much @Constantine. I am looking forward to fixing this problem on nextcloud. By the way, this problem does not exist on owncloud. It is completely normal to use it on owncloud !

Hello again @Jackson
We have just released new version of the connector app for Nextcloud.
Unfortunately, the issue described in this thread is a technically quite complicated then we thought so in this release it wasn’t fixed yet. We are doing our best to find the solution as fast as possible but I cannot provide any estimated time frames of the fix release for now.
Please accept our apologies for the inconvenience caused.

Thank you very much, @Constantine. I hope this bug can be fixed as soon as possible. I looked at the error message and speculated that the problem was caused by the browser’s permission policy when calling the fullScreen method. In today’s browsers, full screen operations must be triggered by the user and executed under user interaction (such as clicking). Therefore, can this method be bound to user events to ensure security and correctness. For example, you can add an event listener to execute the fullScreen method when a user clicks a button? I’m also a simple guess, I don’t know if it’s correct. I hope there’s a solution!
Best regards!

Hello @Jackson
Indeed, the issue is related to the Permission Policy, we are analyzing it to find out where it comes from and how to fix it. I’m afraid it is not that simple as it seems.
Anyway, thank you for showing interest in solving this issue.

Hello @Constantine
OK, I understand. It is indeed a relatively complex issue. I will also try to modify the connector code when I have time to see if it can work. If you have fixed this issue, please remind me on this thread!
Best regards
