Yupp.
It seems to work really well on certain devices, and really bad on others. Didn't work good on four of my last five phones, and only on one of my two three tablets.
Works flawless for me at the moment.
I always had the server issue, but now is during login.
I cant even login
I usually resolve such issues by trying four times and then throwing the phone in the wall, so cant help you out =/
And how do you expect anything to work if you do that?
I wonder if the connecting bugs, or waiting for server endlessly making it unusable for some... could be due to high item count on the avatar? since the app seems to load every item in your account, maybe it that count is over 1k? or 10k? or 20k? items .... that is what makes it so sluggish? I wasn't even able to list an item on auction when I tried it.
