Unable to Access Workspace After Upgrading to Premium

I recently upgraded my account to the Premium plan, but since the upgrade, I’ve been unable to access my workspaces. The platform remains stuck on the following URL:

https://USERNAME.app.n8n.cloud/

Even after restarting the workspace, the issue persists. However, I was able to extract a list of all my workspaces and confirm that none of them were deleted.

What could be the problem? Meanwhile i’ve sent an email to the support team..
