Release 1.6.0 is very slow

### Steps to reproduce

1. Install 1.6.0
2. Use it normally

### Outcome

#### What did you expect?

I expected the app to not be slower, I even hoped for it to get faster thanks to the new Rust SDK.

#### What happened instead?

The app is even more unbearably slow than it was before. Sending messages takes up to several seconds, which some friends of mine who also updated, confirmed as well. Also, for me loading the home screen now takes about 10 seconds. I'm sorry that I can't really pinpoint this any further, but it's really just slower all around and I thought you might want to know. Again, this isn't just me, friends on other devices reported the same.
