I an audiobook collection and am trying to figure out a free way to keep my audiobooks in sync across devices. A friend of mine recommended I check out the gPodderSync plugin for NextCloud. I wrote a PHP script to create the RSS feeds for each audiobook and another PHP script to create an OPML file so I can import all audiobooks into AntennaPod or Kasts. The problem I am having is that gPodderSync doesn't list all the audiobooks that I have. It only lists a small portion of them. Is there something wrong with my scripts or does gPodderSync have a limit on how many podcasts it can handle?
