Tried on matrix.org and it seems to be doing the same there but this time I really had to enter the full ID because for some reason it didn't find anything when I just typed the beginning of the username - probably because I had just created the new user for testing (might be related to Android).

**Smartphone (please complete the following information):**
- Device: xiaomi 8 pro
- OS: Android 9

**Additional context**
- newest version on Google Play (1.0.8)
- Homeserver: matrix.org
