I have an app I wrote in Qt Creator that for months ran reliably when backgrounded on my iPhone. Just recently I upgraded AppStudio to v 1.4 which also laid down AppFramework 1.4.18, Qt version 5.8.0 and ArcGIS Runtime SDK for Qt version 10.2.6.1628.
After re-Making my app and redeploying it, it no longer runs when backgrounded on my device. I may have made some inadvertent change but don't think so. I have verified "backgroundLocation": true, in appinfo.json but have no idea what else to check.
What would cause it to no longer function while backgrounded?
Any and all help appreciated.
