Recently, if I am playing audio from Firefox on my phone, the audio stops when my phone screen is locked. This did not used to happen and does not happen if I play the same audio from Safari. I am using an iPhone 17 Pro running iOS 26.1. I have tried resetting the phone and removing and reinstalling Firefox, but it persists. The problem does not occur with audio played from the same webpage through Firefox using my iPad, logged into the same Firefox account.
