The majority of addresses are wos, using the amethyst, alby, with nwc. Wos i cannot zap using the 1 click zap. But i found that if i go to acct directly, and click on the wos address, i can usually send a zap that way. But on non wos addresses, it usually goes thru with 1 click feature, but very slow, and sometimes i dont see a verification.
