Bluetooth Devices Disappear When 4+ Devices Are Connected

[jslyonnais]

I'm encountering an issue where my Bluetooth devices disappear from my device list after a few hours of inactivity, but only when I have 4 or more devices connected. This necessitates re-pairing the devices each time I want to use them. The issue affects multiple devices including my Mac, watch, headphones, and speaker.

Steps to Reproduce:

• Connect 4 or more of the mentioned Bluetooth devices to my phone.
• Leave the devices inactive for a few hours.
• Attempt to reconnect the last sync devices, only to find it missing from the list of available devices, but the other ones are still there.

Expected Behavior

The Bluetooth devices should remain paired and visible in the device list even after periods of inactivity, regardless of the number of connected devices.

Actual Behavior

When 4 or more devices are connected, the last one disappear from the list after a few hours of inactivity, requiring a re-pairing process each time I want to use them.

Additional Information:

• The issue does not occur when fewer than 4 devices are connected.
• No error messages are displayed during this process.
• The issue persists across different devices and scenarios (e.g., removing one device and adding another does not resolve the issue when the total number of devices is 4 or more).
• I have tried resetting the Bluetooth on my phone, reboot, but the problem remains unresolved.
• I've try with multiple devices, the 4th one is not always the same, but got the same behavior (the other 3 one stay, even if I shuffle the devices, between speaker, laptop, watch, headphone 1 & 2, etc.)

Is there any additional information or troubleshooting steps I can provide to help diagnose this issue? Thanks
