Hey @marcsyp so the nightly builds are including a lot of changes that we are still activity updating.
A big change is how app look and transition on ios and android devices.
Each platform will follow the standard conventions (ios have centered titles and bottom tabs, android having left titles and tabs below the header-bar)
Take a read at his post
All of this is being made configurable as well, so if this isn’t something you would want, you can turn it off.
