Meetings in a recurring series disappearing

[Birdbongos]

Hello all,

I have a problem with meetings disappearing from an existing meeting series. I have external attendees already registered for this meeting series and now see that the first meeting is missing and the three meetings are no longer a series. The last meeting of the series is now also gone. I checked my email to see if I had accidentally deleted them but I have nothing from zoom for these meetings.

These are all created using a template so not sure what's gone wrong. I just used the same template to recreate the meeting series and it looks totally normal. Anyone have any ideas?

Also, bonus question: Is the only way forward to have my participants re-register to a new meeting series or can I salvage the first one somehow?
