iPad app won't let me log in - please help!

I also got the same issue. Poor....

I have seen before that if you have non-standard ASCII characters, or a very complicated password it can cause issues. 

It maybe worth, just until the devices are linked (as you only need do it once) changing your password at www.dropbox.com/account to something easier and then once linked change it back. 

Hi I'm having this issue as well on both iPad and iPhone. My password isn't complicated at all! Help!!! 

Help!!! 

Did you try what I already suggested and reset the password to relink?

Yes I tried that and it didn't work. Any other ideas? 

What an inconvenience, i also have the same issue...
i tried resetting my password thrice. and it still keeps on telling me "login failed"
i tried redownloading the app on my phone. the issue still persists. >:|

ANY OTHER IDEAAAAS?

Same problem.  No joy on any mobile devices but I can sign in on the desktop NO PROBLEM.  I have changed my password three times, each time making it simpler and nothing works.  

Unfortunately, not being able to access drop box on my devices literally cripples the software that I just paid for to work on and sync across desktop and devices.  This stinks.

Which version of Dropbox / mobile OS are you using? 

I'm wondering if its a compatibility issue.

ive got the same problem. 

Annoying af. Travelling - only have my iPad. Need to update an invoice. Can't.

Changed password twice. Can login via safari, app tells me incorrect password. 

So stupid. So so stupid. Dunno what's up, but this needs to be fixed. And I keep getting spammed to buy more space... seems like an elemantary problem - yet here we are.
