I also experience this issue, I thought that it was only me. I think there is some problem on mew these days, at first I experienced some delays, but now I cant send funds.

You should wait until it is successful for you to see it in frkdelta or wait for it to fail for it to go back to your wallet since ethereum transactions are irreversible. It also applies to other crypto. Can I ask you to put your txid here, I might be able to tell why your transaction isn't confirmed yet. Most probably you used low amount in gas. Next time refer to ethgas station for optimal fees(in gwei).
