Damn, @kel is awesome.
Another thing to consider: the app is basically a use-specific, customized browser. Just switch to the web interface by using your phone's browser to use CoSo, and you can uninstall the app, save some space/processing.
The interface is basically the same when the browser display is narrow enough (e.g. on a phone portrait display), but you can also landscape to access the browser-only features and functions you can't get to on the app.
@FernLovebond @kel thanks y'all. The app fixed itself. Possibly related, I disabled duckduckgo tracking protection on the coso app. Initially nothing changed, but since things are now back to normal it's possible it was interfering. Also possible the cache got stale, rotated.
@b4cks4w Settings -> Apps -> CounterSocial -> Storage -> Clear Cache
That should fix it. #CoSoTips
