I just pledged to someone yesterday and I got the confirmation email today, but when I checked my bank account app, I was charged twice.
Hey @charlottemac,
Nick here from the Patreon Platform team.
This is an issue better suited for our Community Happiness team as these forums are more geared towards technical issues with the Patreon API, rather than general product support.
The Community Happiness team can be reached at https://www.patreon.com/faq, they will be able to better assist with this.
