Air Pro 4 - Connection Problems with my PC

I have similar issue. I need to test more, but when "dual connection" is active and buds are connected to phone and PC, the sound in Windows 11 is continuosly "blinking", making impossible to listen to anything. No disconnection message for me, just the sound disappearing continuosly. I need to test without dual mode connected for longer to see if then sound is stable, but I hope someone can offer a solution for this. I have no issues with a different computer and Windows 10 installed.

I had a few minor issues with them connecting to my laptop when I first got them.  However, since updating to the latest firmware (currently  0.3.5), the Air Pro 4's and my laptop absolutely hate each other.  I need to delete and re-pair the connection after every disconnect.  I've tested both in Windows 11 and Linux Mint 22.1 on the same laptop.  My laptop has an Intel Corp. Bluetooth 9460/9560 chip with bluetooth 5.1.  And, when I can get the Air Pro 4's to connect, the range is pretty bad with stuttering within 3 meters of the laptop.  I'd like to just blame this on a hardware incompatibility but, seeing the issue increase in severity after the firmware update makes me hopeful that this could be corrected or improved with subsequent updates.

Good to see I'm not alone with this.

I hear frequently the "disconnected" followed by "connected" sound when my Air Pro 4 are connected to both smartphone (Pixel 8 Pro) and laptop (Framework laptop 13 with this adapter 01:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter).

Firmware is up to date according to the app (0.3.5). I also tried to reset the earbuds and re-pair them to both smartphone and laptop, to no avail.

Seems somehow to be related to dual connectivity, i.e. when the buds are connected to two devices at the same time.

Happens to me aswell.
another issue I found is often the right bud is starting to make sound in a latency of a few seconds, compared to the left bud that instantly plays the sound (they are syncronized in sound, just really inconveniet that it takes more time for the right one to start making sound).
