Home page stays on template page after logging into the mobile app

So I logged into my account today on my mobile phone and I noticed right away that the theme didn’t change to dark mode and that my username or my friends didn’t show up on the home page. Everything else worked fine (minus the theme) besides that. Happens 80% of the time and updates back right after you reopen the app.

I reproduced it on a iPhone XR with iOS 13.3.1
