Are you using Tor? Cache is limited by total available space, do you have more than 10% free space on your device? Profiles load slowly on slow Internet / poor WiFi.

I fixed this by "Settings -> privacy options -> uncheck untrusted relays forcing tor"

I've ran into this as well and it usually resolved with a force close and then they populate on the next open.

Same here. It's not tor-related. Data wipe/reinstall didn't fix it, and it did it across a couple of Amy releases, so not version-specific. If I search for that user, assuming I know who it actually is, it comes right back.

Same here, disabling tor on untrusted relays helped a little but not completely. Also most blossom content shows only the URL.
