Bontrager Ion Pro RT and Flare RT disconnects after Edge wakes up

Hi,

I bought Edge 840 recently with bontrager lights. After pairing the lights, they seem to work correctly for some time, but after a few times when Edge is put to sleep and woken up, the light (one or both) cannot connect anymore. It looks like the problem hits Ion Pro RT more often than Flare RT.

When such problem occurs, the only way to have the light to connect again is to factory reset the light, remove the light from Edge and pair it again. Then the light work again until one of the sleep/wake-up cycles. Rebooting Edge does not help.

Other sensors (speed, cadence, HR from 965) works without any problems so far.

Reading on the internet it looks like it's a common problem with 840.

Tested on firmware 9.29.

Any idea what else can I try? Or waiting for an updated firmware is the only thing that was left?

    I'm searching for an evidence that this was fixed for a year and yet i found noone who confirms the battery bug of small Bontrager front and rear lights and the pairing issue is gone. I've seen tons of combinations of Garmin devices and Bontrager lights on this forum and reddit and everybody has the same issue for years til today.
