As the title says, the QR code scanner option is disabled for me in the Gesture settings for Double Press Power Button.
This option was enabled when this feature released in CBT/OBT and I set it then and there. After a couple days it got disabled during OBT. I did report it twice in the specific discord channel for OBT bugs but till now it hasn’t been resolved. Yesterday, I updated to 2.5.1A from OBT but it still hasn’t been fixed.
Making this forum post to shed some light on this issue since the discord channel has been archived I think.
