Over the weekend and at the start of the week, PayPal had an issue that resulted in people being billed but the transaction showing as failed on our end.
If you have signed up for a new subscription, and the transaction is showing as pending on the forum, so you haven't gained floatplane access yet, and you have waited more than 10 minutes after purchasing it in PayPal, please go to https://linustechtips.com/main/failed_transaction_fix.php and follow the instructions. If you have any issues, please send me a PM (hover over my picture or username and click "message"), including the transaction ID, and I will try and sort it out for you.
If you try to subscribe again now, it should work.
