How do you know for sure that you are on the mainnet and not the testnet?
I'm asking because the checkbox under "Device Settings" was checked even tough I specified that I wanted to use the mainnet during the wallet installation process...I have been able to send 1 ARDR to someone on this forum, so it must be OK.
I having a similar problem. I can't log into my Ardor account because it says I'm connected to the testnet, despite the fact that I specifically chose no to the testnet.
