A pop up appears on every page after install, I don't care if it appears only on day +0, +7 and +30 I don't want a freaking message telling me to give you money to get rid of it.
You say that you implemented a pay what you want subscription plan to get rid of the message, but If we don't give you money the message only disappears for 30 days, and even if it worked I don't want to have to give you my email and have a license to not have a pop up on every page.
