Hello and welcome,
Thank you for reaching out and being so thorough in your post. Sorry to hear about guests showing up on the wrong dates :-/
I took a quick look to see if we have any reports aimed to address your concern and came across a logged ticket to improve the recurring event design, specific to what you described. I’ve linked this forum thread to the logged ticket for the developers to review when making improvements.
With that said, I can’t give you a concrete date on when these changes will be included in an upcoming release (it says next release, so that’s a good sign). Keep your eye on our Release Notes for feature and maintenance notes.
Thanks again and please let me know if you have any more questions or concerns. Cheers!
