Prerequisites

• ❗ On the Android/iOS device make sure to have the option Battery saver/Power saving selected

Steps to reproduce

1. Start the AltServer from AltTester Desktop in batchmode
2. Open a mobile instrumented build with matching connection data
3. After the connection is established, put the app in the background
4. Wait 4 minutes until the app disconnected from the AltServer (check the logs)
5. Bring the app back in focus and check the connection status on the AltTester Popup and the AltServer logs

Actual result

AR

After the app is brought back on focus, the AltTester popup shows that the app is Connected... but with the old appId for the former connection with the AltServer and the AltServer logs show that the app did not reconnect.

Additional info

Environment

• sampleGame Android/iOS build instrumented with AltTester Unity SDK from development branch (23.01.24)
• AltTester Desktop from development branch (22.01.24 - commit 341ccc1)

Screenshots

Other notes

• the issue is not reproducible with the AltTester Desktop in GUI mode
• only after restarting the connection data from the AltTester popup the app can reconnect to the AltServer
• if the prerequisite described at the beginning of this ticket is not complied with the app will not disconnect after being put in the background
• issue found while testing [Concurrency] [AltTester popup] Message remains Connected... after stopping AltServer started in batchmode #1482

Expected result

ER

After the app is brought back on focus, the AltTester popup should show that the app is Connected... with a new appId for the new connection with the AltServer and the AltServer logs should show that the app reconnected.

Still reproducible with v 2.1.0 but after this version changes the AppId is expected to remain the same until the connection data is restarted.
