I reported this already on the Matrix chat, but I will write here so it doesn't get lost.
Since one of the last releases, either 2025030700, 2025030800 or 2025030900, the feature to turn off Bluetooth stopped working reliably. In particular, before these updates, Bluetooth would not be turned off if any device is connected to the phone. Now, it always turns off after the configured time, even if a device is connected (a Pixel Watch 2 in my case).
The "Turn off Wi-Fi automatically" feature seems to continue working correctly as before the update.
Perhaps an Android 15 QPR2 bug? Anyone else having the same issue?
