1) You have to increase the #VersionCode in 'Main' for a new release in Google Play.
2) The minSdkVersion defines on which Android versions the app can be installed. Probably your device runs an older Android version.
3) targetSdkVersion should be 29 at the moment.
4) My experience is that it takes about 5-7 days for a completely new app to be approved. It's mainly caused by the IARC content rating. Updates are usually approved within a couple of hours.
