We have seen the issue come back again with two more failed refreshes ☹️

 

Anyone seen the same? I've now put in a complaint with Microsoft about how our support case has been handled.

 

If anyone else has raised their issue with Microsoft and would be willing to share their support case numbers please post them here so I can share with MS.

 

Ours is 2301160050000773.

    Also had some refresh failures over the weekend with the "handshake" error among others.  However, so far this morning all refreshes successful again.

    I was getting it sporadically on Friday and over the weekend but so far, everything this morning seems to be completing OK. 🤞

    We've not raised the issue directly with Microsoft.  Just monitoring for updates on here.
