I'm using the app and it keeps me logged in so why does it want to register my device everytime i use it leaving me unable to register new ones after 5 goes? This stupidty has been like this for years.

Mine has used up all devices and i use the app on Windows. Can somebody reset them please?

All of a sudden it's asking me to add extra devices again everytime i log in. Now i've reached the maximum limit and can't login. Why?! It did this before but not for a while. Now i can't use the service and i need to.
