TL;DR: questions:
EDIT: I'm not aking how to fix it for a single community, I'm asking how to handle it for >200 subscriptions (thanks!)

• If a community says "Subscribe pending", is it possible that their posts do not appear on the feed?
• If the answer to the previous question is yes: is there any script to fix "Subscribe pending" issues on batch?

Long version:

I started using Lemmy some days ago and when subscribing to some communities (on other instances) I got the "Subscribe pending" message. I'm aware it's a common issue (see search for Subscribe pending in this community) but, because what I read is that the bug was the message itself (but you were indeed subscribed) I ignored them.

Today I took a look again at the issue and I saw that some people recommend un-subbing and re-subbing again. The thing is, now I'm subscribed to more than 200 communities, so it would take a while to do it manually.

Thanks!
