I have a gift cert for Lava Brand website and wondering people experiences with different sizes:

I'm looking at either the custom cool 17"/32oz

OR

16.3oz 52oz

The 16.3 only has two color options with a brushed metal look base:

Blue liquid /yellow wax (appears green)

Purple liquid /yellow wax (appears red orange)

Whereas the 16.3oz I can choose the liquid/wax color as well as the base colors.

Of course I'd like the choice in liquid/wax but does the 16.3 flow better?

I have like 18 blue switches and I keep trying to update them to 3.4 from 2.18. They will say successful and report they took 3.14 but then next time I check usually the following day they're all back to 2.18. I am only updating 1 at a time to not overwhelm the network.

I'm using Z2MQTT.

Thanks to users below I checked Inovelli website and they say to contact them: https://help.inovelli.com/en/articles/13566202-blue-series-switch-troubleshooting-ota-over-the-air-updates

My exact symptoms are listed:
The OTA process reached 100%

The switch rebooted afterward

The switch allows the same firmware file to be applied again and repeats the process
