Hi and welcome back,
I tested to see if I was able to reproduce your issue, but I get the calendar/month view on desktop and list view on mobile – which is what I have my settings set to in Events > Settings > Display.
I see you checked ‘Yes’ to reverting back to the default WordPress theme and deactivating all plugins other than ours as instructed in the Testing for conflicts guide, but can you please confirm this?
It would be best if you could test again, but this time ensure WP_DEBUG and WP_DEBUG_LOG are enabled on your site’s wp-config.php file. Any errors will display at the top of your page as you try to reproduce the conflict. I also recommend right-clicking your mouse and opening the ‘Inspect’ tool to see if any errors display in the console. Note what you find and please include it in your reply.
I’d also review Events > Help > Recent Template Changes to see if there’s the possibility any overrides you have in [your-theme]/tribe-events might contain incorrect/outdated code. Let me know what you find and have a pleasant rest of your day. Cheers!
