Hello,
My Fitbit Sense has got a weird bug. Music controls do not work as intended. The Next Song button reduces the volume, while the Previous Song button increases the volume. The volume buttons themselves work as intended. My phone is a Xiaomi Mi 9, running Android 10, on MIUI Global 12.0.4 Stable. My Fitbit Sense is on Version 44.128.4.17.
I have followed the bellow linked solution. Unpaired, repaired, restarted phone, restarted fitbit. Nothing has worked. Any ideas?
