I'll go ahead and second this. I'm going through and echoing my all time favorites which is painfully slow without caching. On a related point that others have already mentioned, a PWA would likely not suffer from this performance issue.
hey zukken, are you using Android as well? just looking to confirm it is an android only issue. Also saw your other comment, just tried emailing myself using my second email and it worked. (just to confirm it's dan@echopodcasts.com)
