Hi Milan,
Thank you for the update and the effort put into this.
We don’t have any problems with the plugin, except for one weird thing.
As you can see from the screenshot below, there are 2 users that bought and registered their codes in the same month with a difference of a few days, but for one user, it says “Expired”, and for the other one it says it “Supported” until the date that has already passed.

After update I haven’t seen any activity from these members, so perhaps there is no problem at all.
