What's new in this PR?

Issues

In Android code there are still some Material2 elements being used even though we agreed to not use it anymore in favor of Material3. This results in for instance app’s theme not being able to apply colors properly when Material2 element is used inside Material3 one.

Solutions

We removed or updated all elements that was making us to keep Material2 in the project, but now it can be removed completely, so that's what this PR is about.
