Check you emails because if it was only a few weeks ago that you upgraded, then I believe you may fall under the "grace period" category of customer. Double check the information pages on "Studio one 5 grace period" upgrades. I didn't fall in that group but I believe that any one who purchased the upgrade after April 2020 (the exact date escapes me), is entitled the free upgrade. Don't quote me before double checking what I have said.
