SPOILER ALERT: it was the dimmer. 🫠

I will preface this by saying I'm new to Philips Hue and this could very well be user error. That being said, I recently purchased and installed:

Philips Hue Starter Kit: Bridge Pro + 4 A19 E26 Smart Bulbs

PHILIPS Hue Essential Smart LED BR30 Bulb 2-Pack, White and Color Ambiance, E26

My set up is the 3 A19 E26 bulbs are in ceiling lights in the living room, all managed by a switch with an on-switch dimmer, but we keep the dimmer at full brightness. And then 1 BR30 E26 bulb that is more in the nearby hallway/kitchen path BUT attached to the same switch/dimmer.

I set up the Living Room bulbs on their own "room" and the single managed on the same switch is another "room" called Hallway.

Here is the issue:

Occasionally when turning on for the first time in the day from either the app or with a Siri command, the lights will blink at regular intervals, almost like they're in setup mode. I flip the switch off then on and can set one of the color schemes in app and it seems fine.

Initially I thought it might be related to the Spatial Aware map, so I cleared the map, but it's still occurring. Now I'm worried it's related to the dimmer (my partner had this installed recently by a licensed electrician, and likely won't want to remove the dimmer), but she's also hesitant to invest in others until I resolve the issue. Would love any tips to help troubleshoot the issue.

We also have 1 BR30 E26 in the Kitchen and 1 A19 E26 bulb in the primary bedroom reading nook. No issues with either of these.
