Seems to be working fine for Primal, Yakihonne, Nostur, and others.
Discussion
Yeah, don’t know how Nostur and YakiHonne worked around it, but in the case of Primal, I heard Apple takes a cut of the sats you purchase through their app 🧐
Not a cut of sats, but there is a premium on in-app purchases because of Apple’s policies. Easy solution is to send sats to your Primal wallet from any other Lightning wallet and use those for zapping.
