Add as many details as possible. Also provide a link to the video where you encountered the issue.

So you’ve been using the add-on for 7 days and it was working as expected. The notification you mention is a one-time, dismissible message that can also be permanently disabled in a single click.
Its only purpose is to inform users that they can support the project if they wish. This is entirely optional. The add-on remains fully functional regardless of whether a user decides to contribute or not—no features are restricted.
Even if you choose not to contribute, it’s hard to see how a one-time notification could significantly impact the overall experience.
Given this, a 1-star rating seems disproportionate and unfair.

v2.23.0 fixes this.

Can you be more precise, what happened exactly, on which youtube page, what did you do etc..
