App Acknowledgement Obscured on Mobile When No Primary Navigation Bar Present

[lochtefeldm]

Is this something anyone can think of a solution to besides enabling a primary navigation bar? As you see rotating the screen does allow for it to be acknowledged, but for users its not intuitive. Would like to avoid using the primary navigation bar in an effort to keep things really simple for users that will be 60+, and to maximize screen availability on mobile.
It seems like it could be a simple adjustment from the appsheet team could make, check if views in primary navigation if not adjust acknowledgment button placement on mobile.
