I submitted this feedback to the developers as well, but received no response. I pay for cellular data by the gig, so the first thing I did after downloading PodcastApp was use PodcastApp 's settings to turn cellular data off for downloads and streaming. Still (with those settings off), PodcastApp used 1.4gb of data overnight downloading podcasts. As someone who is meticulous about data consumption, this was an unacceptable surprise.
Separately, I experienced other buggy issues. When another podcast automatically starts after one has concluded, the audio was always silent. I had to pause and unpause in order to hear the podcast. Also, while I could unpause podcasts using my Bluetooth controls, I could not pause podcasts using the controls. This is something I only experienced in PodcastApp, and it never occurs when using another audio app.
Given the bugs and the unacceptable behavior of PodcastApp 's settings, this is a 1 star app that I can't recommend to anyone. Deleted.
