Am I right in thinking that once you've had a Developer account for a year, if you study again for an exam you can't use the Azure sandboxes again? I don't seem to have an Azure subscription now although my developer account has been extended until October. So I can't currently do any more sandboxes in Azure. When I try to open a new free account for Azure, I'm told I can't because I already have a developer account. I get that Microsoft don't want to offer free Azure indefinitely but I'm wondering if I'm experiencing a technical issue or if that is a new policy, that you can't even use Azure to use the sandboxes now. I haven't checked the others but was hoping to do PowerApps next week.
