Yes, I had the app from the app store and was using it iPhone 6S fine. When got iPhoneX app was not able to login, hanged. Anyways to day the update was available (from the US store). I installed it and when logged in got Error 500. But ignored it and the app get thru. Working fine, so it seems all good. Thank you for the update!
Especially excited to get it as going to Europe trip next month, so it'd be great to have newer camera and your handy app to on the road! Woohoo! :)
Nice to hear this
