I have ~50 communities subscribed, none of them are empty, and when I use a desktop site, the subscribed feed loads fine. However when I use sync, it loads no posts and I get the message "this community has no posts" (as in the screenshot). I also have an alt account that doesn't have this problem. It kind of kills the app's usefulness for this account. I'm confused and not sure what to do about it.
To fix this I had to log out on the app, like click the little minis, and then log back in
ah, logging back out and in fixed it. weird. now I feel silly for not trying that first, but thanks
