Hi, Joanna. Thanks for your candid feedback.
Your screenshot of Event times does not look like our styling. Maybe it’s coming from your theme (might be this theme?) styling applying to our content (purposefully or not).
The Community Events form did get a design refresh recently (it’s clear you’re not liking the changes).
As far as the calendar’s display goes, we do have Display Options where you could switch from Tribe Events to Full or Skeleton styling and then add your own styling enhancements from there. (Note that switching doesn’t affect Community Events’ styling.)
I’d suggest trying a WordPress default theme like Twenty Fifteen, Twenty Sixteen, Twenty Seventeen, etc. and see how you like the styling like that.
Of course, we always recommend restorable database and file backups before modifying anything on your site. And it’s also advisable to do such changes on a staging/development site and then push to production site once ready.
Once you give things a spin separate from your current theme, please feel free to share specific design suggestions you might have.
I’m looking forward to hearing back from you.
