I’m experiencing the same issue. More things to report.
The XML has the correct skip intro times on it, so from the PMS side everything is correct.
On the client side, if I play one episode the skip intro is also shown at the correct time.
From second episode onwards, skip intro is wrong. Say when binging multiple episodes of the same season.
However, if you close media player and open that episode again (so now it’s the first episode), it’s on the correct spot.
I believe it has something to do with the next episode not syncing time correctly iwth skip intro when played in succession.
All my clients (windows, android, fireTV) exhibit this.
