I'm not sure but there are a lot of people complaining about them recently so If I were you, I wouldn't use them now.
Have Blockchain.info sorted out their issues yet? It's been a few weeks since your post, when do you think their processing will be back to normal?
I've seen problems with blockchain.info recently, but most of them are regarding the UI and not actually people's accounts being hacked, or them being locked out of their accounts. It's either some field, or button isn't working.
Since i'm still hearing about these complaints i wouldn't say that the issues have been "sorted out" yet. And that problem won't be resolved unless they address it on a large scale in the site, and redesign it to make it bugless. Another guy on the forum said that blockchain.info wouldn't let him send any amount of btc, no matter how high he set the transaction fees to be.
As potato chips said, if you really need to access your funds, then import your mnemonics to electrum/exodus/any other BIP39 supporting wallets. I'd recommend moving your wallet/funds to electrum permanently, or until blockchain.info sorts out their problems.
This situation isnt really alarming but quiet irritating. I might not experience such problem but there are still people who do experience it up to now.About on having a notification is really important if they did already fixed this problem or not. I might even believed that having problem on input boxes are just because of net connection but im entirely wrong on my assumption.Electrum is much a better choice than on any web wallet.
