Thanks to R.Fox for the email.
„I knew something was up when the Amazon Prime Gaming connection with World of Tanks didn’t show up yesterday or today. So I contacted Amazon Prime Gaming’s support this morning and yup, guess what? AMAZON PRIME GAMING HAS DROPPED THE RELATIONSHIP WITH WOT.
Me [6:22:56 AM] : It almost looks like Amazon has dropped World of Tanks? Amazon extended the last monthly package by two weeks and then poof! the whole connection has now disappeared.
Amazon [6:25:15 AM] : I understand you want to get your reward on World of tanks , Upon checking here, World of tanks is no longer available in Prime gaming.
This can be confirmed with Amazon Prime Gaming.”
