Cannot open my account on the dropbox app of my android

We really need to know what the error is....

 the error is that either the email address or password is wrong

Hey Angeles C! Can you please try resetting your Dropbox password as a test, and let me know if that helps?

I have tried innumerable times to access my dropbox account from my new cel phone and I haven´t been able. It gives me an error (email or password are incorrect). I have changed my password several times and still gives me the same error

Thanks for giving that a try, Angeles C. Is there any chance you’ve made an email typo?

If you try to log in to your Dropbox account on the website, are you receiving the same error?

It works on the website. The problem is with the app. I have reloaded the app to start from scratch but it gives me the same error

Hi Angeles C, would you mind checking the connected devices section in the security page in your account settings, to double-check if you have 3 devices linked to your account already?

That would be the limit when using a Basic plan. 

If you only see two devices, please send me a screenshot, while hiding the device names and also a screenshot of the error message you're getting.

Hello, same problem on my App for Android. I can access from a browser (Chrome) but I cannot use the App, it asks for authentication app code (I'm using MS Authenticator) and then I get an "unknown error" message. I attach here the screenshot, it is in italian... 
Everything works fine on my two connected laptops - my android phon is the 3rd conncted device.
