What relays are you using for NWC? I get rate limited fast on public ones...
Discussion
The getalby one is intended for NWC use.

Would be nice if clients used more than a single relay though, so connections would have more redundancy.
I'm using my own relay now, but i tested the alby relay and atleast it didn't complain about content length or a few transactions done. I did not test multiple different NWC's with different pubkeys on the same relay tho. Definitely the best public relay yet!
