I have, for several years, used Castro to listen to audio lectures (not podcasts) by loading them into the app via the icloud casto sideloads folder.
In the last week (since I upgraded to a new iphone with the new os) it’s become almost impossible to download and play any of the lectures.
The same thing is happening on my iPad.
I’ve tried deleting the app and reinstalling it. I’ve tried deleting the sideloads folder.
No other apps are giving me trouble.
Nothing I’ve tried to fix it works … and it’s making me sad 
Is anyone else experiencing similiar problems?
Does anyone have any advice?
Seeing the same thing. My last sideload to show up was on the 4th. Refreshing the sideload feed also gives a 404. I contacted support.
oooh. interesting!
how did you contact support? I couldn’t track them down (and am feeling silly for this)
No worries! I’m glad you posted it; I’d not noticed yet. You can contact support with automatically attached logs from Settings > Support in the app, or just email support@castro.fm.
They’ve already replied to me with a question, so they’re at least looking at it…
Are yours working again? Mine piled back into the inbox, which took about a minute to sort out, but they queue and play.
