Anyone got a fix to refresh rate issue when connected to AVR > TV with firestick 4k ?

I'm actually fighting this myself too, not having proper passthrough is one thing but this one is really breaking the experience when running the FireTV through my Yamaha AV receiver. If anyone has a workaround for this I'd love to hear about it as well.

I'm wondering if some edid spoofing adapter would help here, basically force FireTV to always think the end device is connected regardless what the AV receiver does.

I actually got some HDMI splitter here that has EDID copy functionality and that actually seemed to do the trick for this one. So far Kodi nor FireTV has lost the projectors supported refresh rates despite having powered off the systems many times now, been solid at least of one day which is progress
