Is anyone else having issues pairing the varia rtl510 and ut800 to the vivoactive 4? I initially paired the rtl510 as a radar and then the ut800. Then I read that the rtl510 could additionally be paired as a light, as soon as I did that the ut800 got disconnected and would no longer connect. So I removed all the paired lights in order to start from scratch but now the lights will not pair at all, the vivoactive 4 does not find them when adding them as light sensors.
