We lost our licenses on 2021-07-14 so all donations after 2020-07-14 count towards the Plesk transfer order. Your donation was in 2019 so it is outside the range.
For now it only affects new VPS. Existing VPS can continue with the sale price for now. We may end the sale price for existing VPS at some point in the future and then people would be able to pay $3 more per month to keep their memory, or pay the same amount as before but have 1 GB less memory. There is no set date for the sale price to end for existing VPS at this time.
I found this in the log
