This shouldnāt cause your balance to be zero. Iām pretty sure this is a bter issue, my mobile app (bitcoin checker) also has issues updating price feeds from Bter, occasionally throwing errors out while other exchanges donāt do anything of the sort. Of course, that app is completely third party and has nothing to do with Nu, so Iām reasonably convinced this is a Bter issue. Again, it shouldnāt be failing to credit you, that is probably another issue.
I could be completely wrong, but this issue didnāt come about until recently and I actually havenāt changed the CNY server software in a very long time.
