UE4.26 unable to launch game on Quest v28

After updating to the Oculus branch of UE4 4.26.2 we can no longer launch our game builds on quests with versions lower than v30 (maybe 29).
We have 2 headsets that are stuck on v28. They can't find any newer versions. Tried factory reset and restarting multiple times. 

The following message appears when trying to launch the game: 

Device update in progress 
this app requires the latest Oculus software version. Please leave your headset on, connected to Wi-Fi and plugged into a power source. 
Your headset will restart when the update is complete.

Does anyone know if there's a setting we can change to be able to launch on older versions?
