Why, since I started using this add-on, has my Prime subscription been automatically used on channels I don't even watch? (This has happened for over three months straight, as far as I can see in my subscription history.) I also received a suspension from Twitch for "Automated Account or Bot," accusing me of sending spam messages in chats? Luckily, I was able to appeal successfully. I'm not blaming anyone, but all of this happened to me after I started using this add-on...

-UPDATE-

The password was recently changed, and I've always used two-factor authentication. I've closed all authorized connections to claim Drops, and I don't have any authorized apps using my Twitch account. That's all I can share.
I've currently requested my account details so I can investigate the issue further.
I'll try to provide more information when I have the details.

As others have already commented, the Addon currently doesn't work any more in most cases. The drops where it still works are legacy drop campaigns which can no longer be created from November 11th onwards, and legacy campaigns created before that date will stop to work from December 1st, according to the timeline given under the link https://discuss.dev.twitch.com/t/improving-the-flexibility-of-twitch-drops/46818

In the meantime, drops that actually still CAN be auto-claimed without an update of this addon can be recognized by checking the Twitch user's drop-down menu on a relevant stream: If the drop's progress is still tracked by a progress bar it's a legacy campaign which can be auto-claimed, if it isn't tracked however, it already is a new campaign for which auto-claiming won't work without an update of this addon as of yet.

Doesn't auto-claim drops, unsure about channel points
