Yes, it is very annoying. I get this Twirp error consistently myself.
Twirp Error on puzzles

I’ve been experiencing that error on a sporadic, but very frequent basis for several weeks now on my iPhone app.
It’s even more annoying as failing on a puzzle, exploring the solution and then getting praised by the avatar the same way as if I had actually solved it.
It’s a pretty bad experience.
Was told they already knew about it and were working on a fix, but reading other posts I’m not too sure now…
