I think I know what’s going on.
You’re using Damus’ current App Store version?

Also, can you see this button on Damus? 
Using current App Store version, can’t see that button 
Ok, so the reason why you can’t zap is precisely that. There’s a version under App Store review right now for which the on/off switch website reenables zap functionality. But the version you’re using is not compatible with.
The momentary solution would be to get someone to send you an invite to Damus’ TestFlight, which also works with the on/off switch website.
Wow! All those weeks I was on here thinking it was my fault somehow
No, not your fault at all.
You could also maybe give Plebstr a try. I can’t remember if their current App Store version has zaps or not.
Also, people should ask questions instead they of just throwing a url at you blindly 😂😂
If you’re feeling a little more adventurous you could also try Sideus, which is what I’m currently using actually. I’m waiting for Damus 1.6 to be approved to go back to regular Damus.
Sideus is a form of Damus that preserves zaps. You have to side load it on your iPhone.
Ok, I think a found the TestFlight link for Damus
I’m not very technically adept at all so I’ll just stick with what I’ve got here. Honestly I don’t care THAT much about zapping individual notes when I can just zap someone and write a note with the zap. It’s like sending a postcard. Plus, I only ever accumulated a few thousands zaps, which is about equal to a few cups of coffee.
Sure!
