Hi Patricia,
Thanks for you assistance. I was still seeing some of the symptoms on the existing event after applying several theme updates pushed out today, but tried a new test event and it worked. So I deleted the other event, recreated it, and all is working now. Guess it was an Avada update issue, based on timing?
Hoping DST is corrected as well, but will have to wait until Spring 😉
Thanks,
Becky
