I've been using for a while but in the past week the app is requiring full "unrestricted" access in battery management. This was never the case. It used to work well with Optimised but now every time the phone screen is off, the Podcast stops. This is very annoying. I gave it full "unrestricted" but this ended up the app running for HOURS after I stopped using and 3 times now I ended up with almost dead phone because Castbox was using unreasonable amounts of battery in the background.
