Install on new device

i have had to reset my mobile and reinstall all apps including BCN. I purchased this many years ago and have installed it on a number of previous mobiles, it is also currently installed on my Kindle Fire. My account has always been recognised before but this time there is no data (trips, mapfolders, etc.) to be accessed.

The only Google Play account I have is my googlemail one and this has previously worked to upload and install the app. I have tried reinstalling but still no joy.

Can anyone advise?
