We reproduced this bug
It only happens when you play catchup from Single EPG
From the Grid Guide it works fine
We will fix it today or tomorrow in a new Beta Update.
This is how its always worked
- if press Back it switches to live tv (same channel)
- if press Up/Down it switches to Next/Previous channel, catch up stops
So this is just how it works
We have done it this was for 7 years on all our apps
From the Dev Team:
When you press up or down the app switches to the next or previous channel.
It works exactly the same way when catch up is working. The only difference it asks if you want to stop catch up before switching channel.
It is not supposed to stay on the same channel and switch to live if you press up or down
Fixed today in Version 5.0.742 in Beta
Please check and let me know
I think you will need to on Android 9 Buzz box though, as we don't have a Beta list yet for the X5
Use this as a rule of thumb for cache size
1GB of Cache is equal to about 30-60 Mins of Live TV for TimeShift, depending on channel quality
So 10GB would be 5-10 Hours
And yes it overwrites itself once the cache fills up.
