Not-timed puzzle rush - end of session

Hello,

I was doing an not timed puzzle rush that I like to pause and continue whenever I can.
I was on a winning streak with 46 puzzles solved with no error.

However, when I tried going back to it today I got a "your session is over, start a new one" red banner.
I can't see that runin my statistics, everything disappeared, even my score is not registered.

Can you please fix that behavior so that it is at least registered?
If there is some kind of hidden timer (one week?), can't it be reset each time a puzzle is solved?

Thanks

Yes, it is very possible

Just to iterate on that:
My 57 puzzle rush I was streaming for week just did not count https://www.twitch.tv/videos/1161519947?t=1h3m51s

Come on, at least reset the counter each time we open back the puzzle rush!
