At the start of the app it tells me it is transferring data. It fails, telling me it can't use the storage location, even though permissions are allowed. I have not changed any settings for this app. It then tells me to migrate data, so I click ok. It tells me to restart the app. I do this and the cycle starts all over again. Only by selecting "not now" to the data transfer option does the app open. Once in it fails to import new gpx files. I look forward to the day this app just works.
