MuseScore Android doesn't show bottom toolbar

I know that this belongs to
https://musescore.com/groups/musescore-android
but there I cannot add screenshots. So I post here and use the link.

Tapping into the score toggles the toolbars. On my phone toolbars are shown on top and bottom of the screen. On my tablet the bottom toolbar with the transpose button is missing, the top toolbar is shown.
Musecore Android version is the latest 2.2.6. I had a V 2.2.6 before with a different behaviour.

I reported the same issue before for previous versions:
