Glad to hear it is working now! Not sure what the deal was before that it wouldn't work without the CoinOS relay in your regular relay list. This is the only place you need it to show:

I removed #Coinos relays from #Amethyst and tried Zapping. This time it worked. But earlier, as I was, when Zapping wasn't working, I added Coinos relays and then it worked. Weird! But at least it worked now without the relay. Thanks.

Yeah, #Coinos relay showed up here. But I'm not particularly sure whether it was here when zapping wasn't working. I'll keep testing it. Thank you for the tips. Really appreciate it.
