Just now I was copying two mp3 files from cloud to local folder. During that time AP was refreshing podcasts. One of file (already copied) was added to list, second (its copying did not finish) was not visible. So i refreshed list of podcasts again but second file (already copied) did not appear. Going to subscriptions, opening local folder AP follows, file was there so i was able to add it to my playlist from there. Here helped that I knew there are two files, in common podcasts I’m already not sure If i did not miss some.
