Not sure if this is a connect problem or catbox problem, but often when clicking an image hosted on catbox, it'll flash the low res then show a broken image picture when it tries to load the high res version.
Unrelated issue but I've also noticed that occasionally when turning the screen on while viewing an external link in-app, the app will crash.
Same issue for me.
Fun fact it was fixed then broke again then fixed again and now it's broke.
