Can't Local Trade with myself in LGPE using 2 Switches...

[TokoyamiTheDark]

I just received a secondhand Switch, so I decided to trade with myself in LGPE using both Switches. However, even after 10 minutes or so, no Switch can detect the other one via Local Trade (I don't have an account one the newest Switch while my main has no Nintendo Online subscription) In my Pikachu version, I'm at Rock Tunnel while in my Eevee version, I am straight after battling my rival outside Oak's Lab, so trading is enabled in both games. I just don't understand why... so I tested it at a friend's house who has CFW, edited his save file, same thing as an unedited one, even if both of my own switches are perfect clean. What could be the problem?

Are they both on the same firmware?

are they both on OFW?

both games on same software version/revision?

both have flight mode off?
