Stop streaming while signal lost

I using AntennaPod for some months now. Great app, congratulations to all people involved. Before I found AntennaPod, I used Castbox.
Problem: When I listen to podcasts, I often drive in areas without a signal or with a terrible signal. Usually, it lasts some minutes. AntennaPod stops streaming podcasts quite soon after I enter the uncovered area. Castbox worked better in that areas. It looks like that has a bigger cache for streaming. I always use streaming and don’t download a podcast before listening. Is there any way to increase the cache size?
