I cannot stress this enough. If you pledge on my $1 tier through the website, you pay $1, I get about 85c, Patreon and the card processors get about 15c. If you pledge on the same tier through the iOS app, you pay $1.30 and Apple get the extra thirty cents.
Thread. Please, PLEASE, if you support artists on Patreon, use the Patreon WEBSITE to manage your subs, *NEVER* the app.
