Is there a cut-off date for pauses if it affects someone else?
There is no “cut off date” for a pause because the opponent can always resume.
Note that you can still play turns in a game that is paused - this can be useful.
But there is a “mis feature/bug” (IMO) which is that a game that is paused can go into scoring, where the “resume” button is no longer available. Then it is stuck until the players accept the score … or one of them reports it and a moderator calls the game.
I don’t understand that sentence, sorry!
