Trying to pair AirPods PRO but light is flashing amber (2)

After pairing issues with my new AirPods Pro (right earpiece does not connect every other time), I called Apple Service and they replaced the right AirPod. It did not solve the issue, so next time they replaced all three parts: both earpieces and the charging case.

Now I'm having troubles pairing the new set to my iPhone X (same with my iPad pro). I disconnected the old set in the BT settings and deleted them in iCloud.

The following is C&P as it is the same here: They are definitely charged but when they are in the case the light is flashing amber. When I open the case and hold them by my phone, trying to pair them normally, the animation does not show up. I saw recommendations to try to pair them one at a time. When I take out one of the airpods the light is a solid green and I can pair it easily to my phone. However, then when I put the second airpod in the case the light begins to flash amber again. I left them together in the case, like many people said, for a while but the problem was not solved. Then I unpaired that AirPod and did the other one first and the same result happened. C&P ends here

So, I called Apple Service 3rd time and they sent out a second charging case... does not solve the problem. Amber light flashes forever. I tried everything:

• let them rest in the case for 15mins, open lid (amber flashes), press button for 5sec - nothing, light still flashes amber.
• the same result if I press for 30sec or even 2mins - light always flashes amber.
• taking out one earpiece: after few secs the solid green light & I can pair the single earpiece. Works for both sides.
• I can even pair both individually, then play music and combine the output on both earpieces in the airplay settings - result is 2x mono with each one acting individually on a long-press

Please help me! Do I need to ask for my money back? I don't want to as I like them, but not as they are...
