After a version update, connection issues are almost always resolved by making sure both apps are fully updated — ScoreCam and Scoreboard Remote must be on compatible versions.

Steps to restore the connection:

1. Open the App Store and check for updates to both ScoreCam and Scoreboard Remote. Install any available updates.
2. Force-quit both apps and reopen them.
3. Make sure Bluetooth is enabled on both devices.
4. Tap the Remote button in ScoreCam to start advertising, then connect from Scoreboard Remote.
5. If still failing, reinstall both apps from the App Store.
