Oculus Link on Quest 1 changed

Anyone knows what happened to Link on Quest one and when? On the Performance HUD for Link for encode/xfer/decode it used to show 2-5ms encode (depending on the game), under 2ms transfer and around 8-12ms decode latency. All lines were nice and flat except the small jitter. This was still the case yesterday with the PC software updated to v46 but the Quest still on v39. The Quest updated itself to v46 as well overnight and now the Link stats are weird. Encode is now firmly in the 4-5ms area, transfer is up there with encode (the graphs overlap) and decode is jumping between 0 and 8-12ms constantly, it's graph looking like an earthquake graph. Same behaviour on two different machines with both the official Link cable and a normal USB3.0 cable (tests at 1.5 Gbps in the Oculus software).
