I have bought four L510E smart bulbs. I bought all four at the same store at the same time.
When I set the smart bulbs up the first time, 3 of them instantly found new firmware and upgraded to 1.1.7 Build 20201029 Rel. 40821
The last one did not find any new firmware - saying the firmware was up to date, and it running firmware version 1.0.12 Build 20200424 Rel. 54525.
How come one of them isn't finding the new/latest firmware? Can I "force" the firmware upgrade somehow?
