I have uploaded build 3.516 to the usual location:
This build removes the Android APK from the package. Instead, it now needs to be installed from the stores:
Google Play Store: https://play.google.com/store/apps/details?id=org.cybertracker.mobile.ct
Apple App Store: https://apps.apple.com/gb/app/cybertracker/id1524186167
If you need continued support from the old version, please continue to use it.
