Hello,
I am a bit perplexed as to why your new 3rd Gen Yoto player does not support special characters in Wifi passwords. This is a security risk for users to not have special characters.
Further, why does your new 3rd Gen player not support Wifi 5GHz? Many new mesh routers are not configurable to 2.4 GHz.
Overall this is a good piece of hardware, but these two design decisions are highly questionable.
