GEN2 dataflow error - We received multiple duplicate continuation tokens from Azure Storage

I spoke with a Mindtree engineer.  The release train went to production on 4/5 and this unusual error appeared to us for the first time in our daily GEN2 refresh on 4/7.

They want me to open a new ticket (SR). After that Mindtree promised to send the bug to Microsoft via ICM.  They claim there are no prior ICM's with a similar error message yet:

We received multiple duplicate continuation tokens from Azure Storage.

I will probably send this issue thru pro support (Mindtree) once our users start to notice/complain.  It may be a few days for them to realize their stuff is broken (again).  The worst part is that this new problem came up in the same "train" that deployed a fix for a different problem.  A very LARGE part of my job these days involves talking to Mindtree support about Fabric bugs.  Some days I find it very troublesome to be a Fabric customer.
