I completed one of the sponsored offers on the Gaia cash page. It said my Gaia cash would arrive with a fifteen minute delay, but it's been several days and it hasn't come? I did several other Gaia Cash offers immediately before and after and they all worked after only a few minutes (normally I'd wait longer before fussing, but the others all arrived so quickly!).
I got a confirmation email from the sponsor, and I could screenshot that, but I didn't screenshot the page on the sponsor's site.
Also, does anyone know who I should contact? The 'Help' page is out of date (it has screenshots of the old gaia cash offers page with the old "Missing Gaia Cash?" button).
