they are normally pretty on the ball, never had any issues with using them. Kucoin is my exchange of choice when it comes to onion.
Yes, Cryptopia don't seem to get these problems solved. They said a bit ago that they solved the problems but in fact, it seems they are still there :/
Well it's a matter of waiting, I love buying onions in Kucoin, it's much quicker and easier, I trust that they will fix the problem quickly.
I also never experienced any issues with Kucoin and I'm sure they'll fix any problems soon.
I've had loads of problems with cryptopia so kucoin is my goto site now
