My customer does not have a support plan but I was under the impression that basic support was still Included with Dynamics 365 subscription ??
Here are the details from the customer's email.
From Power Platform Admin center, I can’t get to the free support link anymore. The process seems changed or broken. Jon was also unable to find the free option.
Clicked “See Solutions” , and chose “No” on was this helpful
The “Next” button takes me to the Solutions tab and says I do not have permissions.
The Professional No Charge option is gone.
The “Learn More” link takes me to a page that still shows the Professional No Charge support plan.
There is no option to select another support plan.
