Multiplayer mode in Retool Cloud

We have a major issue with the multiplayer mode in Retool Cloud.
As long as now multipage app now is a default way to implement an app with multiple screens, we switched to this approach, and now all the team (3 devs) are working on the same app, but its different pages.
When everyone logs in, the editor shows all the three avatars in the top right corner correctly.
But then, if you leave a page and open a Retool DB, for example, and then return back to the app, the IDE won't show you as active person working.
You will be seeing only you as editor, while others will see themselves only.
But if you will try to change the app, it will say 'failed to save' and error message.

After refreshing, all the changes by the affected editor will be lost
