All SmartThings motion sensors (Samsung) motion detection is heavily delayed

Hi,
A few days ago I noticed that, in some of my rooms, light automations became somehow delayed (by approx. 5 seconds) which is very annoying (standing in the room waiting until lights turn on)
I then figured out that the same issue is present for each light automation which is controlled by ST motion sensor (latest generation). And I have 5 of those. Are you aware of any recent FW update? Or is this a "known issue"?
According to ST my current FW version is 00...014

No problem with IKEA's motion sensors (I have 2 of them) or Hue motion sensor (1x)

I have several generations of Samsung motion sensors and I have had issues with delays on them but they're intermittent. Nothing changed for me recently.

I’d check the connection route in the IDE to see if there happens to be any link along the chain in common for all of the ones that are exhibiting the delay vs ones that aren’t just to rule out a problem repeater.

I've been having intermittent issues with my ST motion sensor automations for a while now (over a month I think). I use Home Assistant for my automations bit I've tracked down the problem to be ST not reporting motion when it should. Sometimes it works perfectly and then other times it's either heavily delayed or just doesn't respond at all. It's such an irritating problem and clearly the result of either a firmware update or core system change. I just wish I wasn't so heavily invested!

Could just be chance, but I have noticed some of my sensors are delayed by just a moment or 2 more than I remember them being not too long ago.
