I am trying to use Apple Pay via iMessenger but it keeps prompting me with the same message, telling me to sign in with the same login in iCloud and iMessage which I have been and already have! I tried restarting my device and it still won't work.

I am trying to use Apple Pay via iMessenger but the same error message shows up telling me that I need to use the same login for iMessenger and iCloud in order to use Apple Pay. I feel like I am going crazy here because I am logged in both on iMessenger and the iCloud with the same login it is prompting me to! I tried restarting my iPad and it still won't work. This is ridiculous! Sorry I am getting frustrated because it keeps prompting me with the same error message even though that is not the problem anymore. Help please!
