Hi Robert, welcome back to the forums!
What you’re describing is correct — the Month View is responsive by default and scales down on smaller screens so that full event titles are no longer displayed in the calendar grid, but as dots on dates that have events with those events listed below the calendar grid.
If you would prefer to remove the small screen view altogether, then you can add this line to your theme’s functions.php file and the full size calendar will be the default view for all screen sizes:
add_filter( 'tribe_events_kill_responsive', '__return_true');
There are also more ways of customizing the responsiveness of the calendar detailed here in this post.
Will this work for you? Please let me know. 🙂
Cheers!
Geoff
