SharePoint Online issues creating site collections via PnP code again...

We are also seeing this issue. It's extremely frustrating as we are trying to deliver a robust provisioning solution to our customers but are impeded by this seemingly inconsistent issue. Most sites go through end-to-end no problem, but every now and then a site will bomb out. The site collection will still get created but the provisioning code will bomb out with:

"Operation is not valid due to the current state of the object"

at 

tenant.CreateSiteCollection(newSite, true, true);

We are attempting to wrap this in some retry logic but we really shouldn't have to. Please fix this Microsoft.
