RCX does not install: unable to parse

[geert56]

Thanks for a great app! I was using AIS Synchro for a while but it always crashed as soon as you try to open a file (download did work though). I successfully installed RCX on my Moto G4 which runs Android 7.0. I imported the previous rclone.conf from AIS Synchro and all works well. However, the same RCX 1.12.2 won't install on Moto E4+ which runs Android 7.1.1. Isn't that strange? By the way, on the Google App Store it says that RCX is incompatible with the Moto E4+. I'd love to use RCX on more of my devices.
