SharePoint Online - Issues Saving Site as Template and Activating .wsp Solutions

We have the same issue across multiple tenants. As far as we can tell the last time this feature worked was about 5 days ago, we've opened a ticket with MS and await a response.

As usual the helpdesk was utterly incompetant and it felt like dealing with Mr Bean or being in a Monty Python sketch, just to get them working on it. Finally aftare complaining and escalating they seem to be taking it seriously.

As an aside, I've never in all my decades in a MS Partner heard my collegues slating MS so hard. Everyone is totally fed up and wishing to retire or do something else. The quality of the SW seems to have fallen dramatically, no testing, no decent documentation,  things that work one day, dont work the next, services are slow and unresponsive, "Maker" experiences are terrible and slow to the point of being infuruating.  Never thought the day would come when I would despise MS. "En****ification" has arrived.
