Once again my wife's Wechat account seems to have blown up. Last time we gave up and simply made a new one.

The password I have written down doesn't seem to work. The mobile number showing on the account I do not recognize--I think maybe it's an old number that has since been changed and I'm sure I updated it on Wechat. Her iPad is logged in but effectively unusable--if her sister calls it will ring but she can't answer, everything else just shows a network error. There's no problem with YouTube on it, though--the network is most certainly working.

It is not anything in the network path, either--as I write this she's using my account off my PC to talk to her sister, no problems.

Any ideas?
