I have an active Export PDF subscription account, but prompted to upgrade.
I cannot currently export PDF documents, but I had used the export feature previously with no problems. Now when attempting to export I am prompted to upgrade from a free subscription.

However I already have a current subscription.

The first time I attempted to follow the upgrade link, the page said I could not purchase a 2nd Export PDF subscription! Now I cannot find that page again - I am taken to my account page instead.
Attempts to find a support channel - or reach ones I do find - are in vain (24x7 account help chat interface not working, etc).
