I hope it is temporary however some people have been waiting months for news on their verification. And there is very little communication about what the issue(s) are.

Coinbase, I haven't used in a while. I know some people that have had issues recently but not to the extent on the smaller Exchanges. I think Coinbase is solid however doesn't trade some of the lesser known coins, so forced to go via Bittrex/ Poloniex at times.
