"All the spam flood clogged our Tor server, so we're having to defrag the 160gig database it's on. Will take a while. Sorry"
I went into settings and stopped using Tor and was successfully able to make transactions. My past transactions that did not appear on the Blockchain, have disappeared and my balance is correct.
Twitter really does seem to be a very good place to get CS as no company wishes to give bad publicity in such a Public Forum.
Thanks for forwarding it here. I rarely use Twitter and it didn't occur to me as a place to look for Mycelium annoucements.
I'm pretty sure I don't use Tor at all. I never enabled it in the settings, and so I guess the Tor server isn't the only server having trouble.
