Send a link to receive payments using email, text or whatsapp

[LesPappII]

I sent a link to people from using the button on my website, but now when they go to it says your session is invalid or expired.

I want a link I can send them that won't expire so they can donate.

I can't find anything in help, or in my tools or profile with a web address that will direct them to my account.

Thanks,

Les
