Aliexpress/Alibaba is broken?

Yes, the app always worked, true.

No problem on the app

Yes, I did receive what I ordered (always did) and the glitch appeared to be temporary. One day, all of a sudden the login started working again, in every browser. The only thing that I thought was strange was that they reverted to the old password. But else all is fine.   

OP: Did you receive what you ordered? And lastly, did you resolve the browser/tracking issue? I have been getting frequent updates regarding shipping, but like you, I am unable to log back in and have tried everything.

TIA

@fuzztone that is not very encouraging, uhmm ..

Even when/if it's working it is not good. Try returning anything there. 

Meh.
