Steps to reproduce
Open a note in Obidian for Iphone and start edit. Your keyboard appears, making the ribbon button inaccessible. This is problematic for the voice recording core plugin since you need to be in edit mode to start/stop the recording.
Be able to click the Ribbon or hide your keyboard.

I can’t reproduce. The keyboard stays hidden for me during recordings using the ribbon command.
Have your tried in restricted mode with no snippets?
An option is to add start and stop to your mobile toolbar. Settings > Options > Mobile → scroll to the bottom → add “Start recording audio” and “Stop recording audio” to your mobile toolbar as a global command and move them to the top(front) of the command list.
