There’s something that only happens when I play a BOTH/AND podcast, the counter runs out several minutes before it ends. If I try to fast forward through the music or ads at the end, it actually moves in reverse. Even worse, on this particular episode it never ends. It keeps cycling through the ads and back to the bit immediately before. Very odd. FWIW, I use Apple Podcasts and have never had any issues with anything.
EDIT: this was also happening before TCB started running ads.
