Whenever I try to view All mentions I get an error message about Unable to load.

Private mentions work fine, as does seeing mentions in my notifications.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to Mentions
2. See error message - "Unable to load mentions."
3. Tap "Private"
4. See "private" mentions
5. Tap "All"
6. See only private mentions
7. Scroll down
8. Get same error.

**Expected behavior**
I see all mentions

I'll try and see if I can reproduce on my laptop later (in which case I can check what response my instance is giving to the request)
