Hey @joyously we are on the same page for sure and think alike 🙂 I actually tried the JQuery Migrate Helper plugin and that did not seem to solve. I actually might try that again as maybe I did not give it enough time. And yes, I do use the WP Downgrade plugin and love that tool!
Thank you again @joyously . We can certainly do this and try. I can tell you that we did disable the plugins one by one and checked to see if the issue was resolved. Did not seem to be a plugin issue. So far the only way to resolve it is to go back to WordPress 5.5 which I hate to do.
Thank you @joyously for your help. It is so much appreciated! I did as you had suggested and am not seeing any Javascript errors. And yes you are correct, it is the links below the main banner image and they do work in Firefox only. Unfortunately not Chrome or Edge.
