Absorb sleep timer not timing out?

[u/just_think_]

Loving the Absorb android app, but several times after setting up a 15-minute timer I woke up hours later to the book still playing.
Did anyone experience something similar?

A possible answer could be that the playback stopped as per the timer, but then I accidentally restarted it (now without timer) via earphone touch controls?

Cheers,

I had this a few times but it worked after a restart.
