Hello. Using Quest and with the current update 16, the app does not stop once recording starts. The stop button does not do anything. I reinstalled the app and its the same.
It is the same for PDF and Web modes. Oh and only tried to with the English version. You maybe using the Japanese version. The Quest OS is on Korean. Same with all default avatars too. Unable to stop recording by point and clicking on the stop button is the same. The exit from the app button works.
Changed my Quest to Korean language and run the app with English mode, but I still cannot replicate the symptom. I may need to update my Quest. I haven't used it for a while.
