No, you can use Wos too, if you don't connect Alby when you click zap it will ask you what wallet you want to use anf you can click Wos.

But I don’t see zap icon on the Post. Same like here only zap on the profile
You have to enable it, click here and follow instructions once you have Damus installed.
Nice!!!! Thanks for this info… so helpful Now I use Damus again… 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
Your welcome, it's kinda confusing. The reason you have to do that now is Apple doesn't like Damus doing zaps cause they think of it as a in app purchase.
