@ruenel Thanks for checking this.
It was strange because it happened randomly and I did not have any caching plugins installed yet. I’ve installed WPRocket and cleared all the caches and everything seems to be working like you said.
EDIT: It only seemed to work for a minute and now no longer shows the changes again.
EDIT: I’ve disabled all browser extensions, and it seems like it has corrected the issue on Mozilla. Chrome seems to work as well. Mozilla was just updated 3 days ago so I wasn’t sure if its related to my current extensions and the new version of Firefox. I will keep editing this same reply if problems resume. Thanks for the help @ruenel.
EDIT: Mozilla 96.0 seems to be the issue. The real-time changes while editing keep stopping, even with all css removed and plugins disabled. No issues with Chrome. I will switch to editing only with Chrome until Mozilla releases a new update.
