Help required.

Yesterday I installed 2off Deco E4 units which worked fine.

This Morning I came to install you 3rd unit and find I am locked out of the Deco App and can not access to install the 3rd unit, 

Password has been reset which worked for a while then locked out again saying wait 2 hours, 2hours later still locked out.

All very frustrating if the app locks out after a few logins
