This certainly sounds odd, @LarryPilkington, I recommend having a go at disabling 'Media and mic' and then performing a soft reset on your phone (press your Side and Volume Down keys together until you see the Samsung logo). When your phone reboots, head back to the screen recorder settings and re-enable 'Media and mic' to see if this helps.
@LarryPilkington Thank you for giving those steps a go. I recommend submitting an Error report to allow our Software Team to investigate this issue further for you. To submit a report:
Your report will then be reviewed and you'll receive a response with a solution via the Members app.
@LarryPilkington: When you head to Settings > Battery and device care > Battery > Background usage limits, have you checked the Sleeping and Deep Sleeping apps categories to see if the Members app is listed here? If it is, tap the 3 dots in the top right of the relevant category > Remove > Tap on Samsung Members, then hit Remove at the bottom of the screen.
