Clock doesn't stop after my move (on Android app)

Sometimes it happens to me that even after my move my clock continues running.
I've lost several games in the past weeks because of this, because even if I had a decent advantage in the game and I was winning, I lost because I ran out of time.
Is this a known bug, a latency issue or some kind of cheat?
It seems like it happens only when I play on my tablet using the android app.
Thanks for any feedback

It's been reported many times already.

Hi
I am playing on Apple IPhone : same problem for a few weeks now :-(((
Which spoils so many games recently
Extremely frustrating as I usually so much time on the app
This a critical bug.
Will stop playing until fixed
—- salut
J’ai le même problème en jouant sur iPhone depuis quelques semaines.
C’est extrêmement frustrant pour moi qui aime tant jouer ici !
C’est un bug critique - je ne peux juste pas jouer et aucun correctif n’est proposé :-(
Vais chercher une autre application d’echecs en attendant que ma favorite soit réparée.
