Hi, We have an app that is free to download and use (provides local info such as defibs, hospitals, tourist hotspots, etc) for a local tourism charity. I have been asked to update the app and provide a donate button in the app so they can take a donation via stripe. My initial thought were Apple would want their 30% of any payments via the app is this still the case for donations and using a 3rd party payment provider like stripe. Could we avoid this by using the button to open a web page on their website to do the payments. thanks
