Why did you remove the change size or add social media sizes to the add + button? And when I change sizes why does it make it all weird, like sizing of objects is off, I can reduce sizes etc...its just a mess!!!
Apologies for the late response and also for the frustration & difficulties you faced with the new Adobe Express. Do you still see the issue of the size not being reduced? Are you getting any error messages? Which browser are you using?
Have you tried using the other suggested browsers (Safari, Microsoft Edge, and Google Chrome) to see if it makes a difference? Try clearing the browser's cache and cookies to check if that helps.
Also, try restarting your computer.
Please let us know if this helps. Also, helps us with a screen recording of the workflow to investigate further.
