Tbh you might be able to come back go pocket casts. They added a bunch of functionality back over time. Can’t remember what it used to be like anymore, but it works for me.
I have a free account and do have access to the filters. You can filter by podcast, started/not started, duration, etc. It may still not work for your needs though.
What’s the point if they still have AMD, Intel, Nvidia, Qualcomm, etc. chips on them?
