Which exchange/wallet do UK users use?

I've been looking to buy RVN for a couple of months and finally bought 1000 this morning. But I made the mistake of buying on Crypto.com who can't receive or send Rvn. As I'm building my Rvn mine this a pain. Who are you guys using for deposits from the mining rig? Also, the RVN app is so poor, does anyone know when this will be in a genuinely usable state not having the never ending "sync"? Really love this community but there are a few obstacles to get to the big leagues.
