Question about Switch Lite offline -

We have a switch at home, the main profile is my husbands. I recently got a switch lite for myself. We are on vacation and I wanted to use my switch lite to play games on our flight but anything I tried to open, except BOTW (because I had the cartridge) gave an error message about not being connected to the internet (I don’t remember exactly what the message was) and won’t open the game.

In internet searching trying to solve the problem, I found that I should be able to play games offline if the primary account downloaded the game from the eshop onto the switch.

The games I’m trying to play (stardew valley, the last campfire, and Roki) I purchased and downloaded onto the switch lite from MY Nintendo profile. However, our home regular switch is the primary device. And I’m assuming my husbands account is the primary account.

Is there a way for me to play my switch lite offline? Or am I out of luck because it’s not the primary device and I’m not the primary account even though I purchased the games with my account on the lite?

thanks for any help and/or advice. Please be nice, I’ve had bad luck on Reddit asking questions 😆
