"The specified thumbnail file is not supported." error in Notebooks

A colleague of mine created a notebook to do some postprocessing for one of my feature services and shared it in a group with me.  I tweaked it a bit, and since the original was owned by him, I was prompted to save my version as a new notebook. After filling in the fields to save it, I received a "The specified thumbnail file is not supported." error and was not allowed to save the notebook. In searching all the settings for the notebook, I don't see that there's been a thumbnail saved to it (there's just the default notebook symbol showing on the item summary page). Any thoughts? My colleague was able to make the same change that I did, in his copy of the notebook, but this isn't a good practice, as I'll have future changes I'll need to make.

Hi - does the original notebook item (the one you are "Saving As" a new version of) have a thumbnail associated with it?  You can check by going to the Item Details of the original notebook item...

Having the same issue. Curious if you've ever figured this one out?

Hi  @FionaBecker , thanks again for bringing this to our attention.  Letting you know that you can expect a fix for this in the summer 2023 ArcGIS Online release and the Enterprise 11.2 release in the fall.
