Thanks for linking that post, totally missed it tbh… I will give a try to those files through this week (I’m going on holidays soon, so my availability is a bit limited), and see if I can replicate.
In the meantime, can you also share the mobile phone model and Android version you are using? Just to see if maybe it’s a device-specific behaviour.
