Private study - suddenly chapters are empty

I do not know how to ensure that.

I mean, it's a 100% private study of my own and always has been. Would there ever be a reason I wouldn't be synchronized?

Also, looks like that must have been the problem, since the button was a play button and changed to a pause button when I just went and checked. Thanks. I must've clicked it by accident and had no idea it existed or what it did. Sorry to disrupt the thread, but I thought my issue could be related and the extra info may have helped.

Maybe this sync mode toggler is the root of all these issues. I have to think about making it more visible - maybe outright disabling it in certain cases.

It could be. I have noticed that moves do not save, even for the study creator, when not synced. It would not be a problem, except sometimes I find myself de synced when returning to an old study and do not notice at first.

I have recently used the wonderful study mode quite heftily. And i've noticed a few things regarding this subject.

First of I always or in most cases want my sync mode off because i just save the initial positions for regular training for myself and others.

So normally lichess never remembers that sync is off for any study. But in some cases when i enter my studies it is turned off even if I didn't have it turned off before. From what i best can tell but not sure this happens when it remembers what chapter i was on and that it doesn't always remember. If i then were to refresh the page i get thrown to first chapter and with sync on.

But please don't remove the ability to not be synced.

Hope this might help best regards.

@thibault it seems that a new case appeared, see:
lichess.org/qa/3096/losing-comments-while-writing-a-study and, according to the OP, he was synchronized with the servers.

What if there were an Edit and a View mode? Basically this is the point of sync button.
