Hi,
We had a similar problem previously.
Devices running iOS 15.4 and VLC 3.3.7 would stop randomly in larger songs - this was resolved by updating to 15.5
Devices running iOS 15.5 and the previous version of VLC would stop randomly in larger songs - this was resolved by updating to VLC 3.3.7
The recent iOS 15.6 update with VLC 3.3.7 appears to have reintroduced this same error.
We manage a fleet of about 100 iPods (and growing).
This is a bit of an urgent issue at this time.
Any help appreciated. Thanks.
