Any view of subreddit posts crashes for me moments after opening. The inbox, search, settings screens are OK.

So this isn't happening to me anymore, maybe it was an API outage upstream?

It’s still happening to me. App crashes when selecting popular posts or any subreddit I subscribe to.
iPhone XS Max
Version 14.4.2

Updating to iOS 14.6 solved the issue for me.

Update: I was able to access the popular posts feed one time and it is back to crashing again.

I am on 14.6 and have similar behavior.

The developer posted a status update on r/ApolloApp:

Argh, looks like Twitter changed their API which Apollo uses, and their old iOS library that Apollo also uses fails very spectacularly if the API changes. Oh joy, ripping it out for now and submitting an update, then I'll rewrite a small version myself.

Not sure why it's only happening for some folks, might be a conditional API change, I thought it might be US based but I still can't trigger it even with a VPN.

I posted essentially this comment in three other issues that seemed to describe the same bug. Sorry for the noise.

FWIW fix has been submitted to Apple, just waiting on approval.
