Unable to edit repeating event

It seems like editing a single event ("Only this event") in a repeating event no longer works. After pressing the Save button, it stays grayed out this shows in the console:
> Unhandled Promise Rejection: TypeError: j.repeatMonthlyWeeks?.join is not a function. (In 'j.repeatMonthlyWeeks?.join(" ")', 'j.repeatMonthlyWeeks?.join' is undefined)

GSD response:

I asked ... if the limitation will be fixed so it works as it used to. They said, "We have submitted feedback asking that they allow all those with access to edit recurring events but haven't heard back from the developers on this one yet. For now, the leaders will have to create a new event with the adjusted information."

I can report that it looks like this is working again. Excellent!

Great news. Nice when things actually get patched instead of us just working around it forever.
