This is only happening for you. Do you have a working lightning address? 
Discussion
It's weird. It works if you zap my post but if you try to zap my via nostr directly it doesn't work but if you type in Craig@store.bitcoin-cats.ca in bluewallet or zeus it works 😅.
I promise I’m trying 😂 
Fuck me. My bitcoin store is down 🥲
Glad I wasn’t the problem. @ me when you’re up and running. I owe you 100sats.
I figured out my issue. I was trying to set up a minecraft server and I ended up fucking up my port forwarding for my node 😅. I fixed it. Craig@store.bitcoin-cats.ca is working as a lightning address and you can donate via my site bitcoin-cats.ca 😅
The lightning address still didn’t work. I was able to do it through your website though with the actual public lightning key. 
Weird lol. When you say website you mean shop.bitcoin-cats.ca or bitcoin-cats.ca/donations. It's all set up via btcpay. I need to study how lightning addresses work 😆. Technically the address on the website is Craig@store.bitcoin-cats.ca 😆. If you zap my post on nostr it should work but if you click on my profile and try to zap it doesn't work for some reason. Idk😅
My node is resyncing atm. 😅 should be fixed in few hours. This has been a great learning experience
