I hate to be a “me too” and not offer any help, but I am experiencing pretty much the same. I bought my first starter pack online. No problems with updating the bridge. I just bought a second one from Home Depot, and the bridge says it needs an update to turn off the blue light, but when I follow the prompts to update for that feature, it says it’s already up to date, even though it shows 0.0.0.30! My first bridge which I was able to update shows 0.0.0.33 and allows me to turn off the blue light. Even in the app where you can select which devices to update (under Account, and then Firmware Upgrade), shows both bridges, but the new bridge from Home Depot shows current and latest versions are both 0.0.0.30, and the old bridge shows versions are 0.0.0.33.
I also tried swapping the .30 bridge into the old camera that did allow for a bridge update. No luck.
I suspect this is a problem with the app, since it already seems to have checked on the version, and doesn’t bother even trying to update the bridge. I have tried resetting the app, clearing data, clearing cache. I’m out of ideas.
