"Black screen" appears when entering SOTI Snap Lockdown Mode after upgrade to 2026.1.1

After upgrading the SOTI Snap Device Agent from 2026.0.0 or 2026.1.0 to 2026.1.1, devices configured to launch a Lockdown App may display a black screen before entering Lockdown mode. Although the SOTI Snap Agent upgrade completes successfully and the Lockdown configuration is available, the Lockdown App is not initialized immediately. This issue occurs only during the first launch after upgrading the SOTI Snap Device Agent from 2026.0.0 or 2026.1.0 to 2026.1.1. 

• SOTI Snap 2026.1.1
• SOTI MobiControl Android Agent 2026.1.4 and below
• Android devices enrolled with SOTI MobiControl and running a SOTI Snap Lockdown App

Users may observe one or more of the following:

• A black screen appears immediately after the SOTI Snap Device Agent upgrade.
• The device does not automatically enter Lockdown mode.
• The Lockdown App does not launch immediately.

The root cause occurs due to a Lockdown initialization synchronization issue between SOTI Snap and SOTI MobiControl after the SOTI Snap device agent upgrade is completed. 

Perform the following steps as a workaround for this issue:

1. When the black screen appears, wait for a few seconds to allow for the Lockdown initialization to start automatically.
2. After a period of time, the lockdown app will initialize successfully.
