I am getting update nags on my Switch (6.2.0 AMS), after my kid inserted the original cart. Not sure if he connected to WiFi too. But, when I try to reset cache with Recovery Mode it automatically turns on WiFi despite it being in Airplane Mode. The game concerned is Flying Red Hat. I am getting a little frustrated here. I install v1.3 update and it crashes. I uninstalled and reinstall the game and nothing.
(Edit)
Same problem with Kaboom Cousins and Brick: Urban Underground. All other backups work. I have already entering Recovery Mode by long pressing both Volume +, Volume -, and Power On. Then releasing Power On. Then it loads the Recovery Mode, instead of getting 'Delete' I get 'Initialize'. Reboot. And the update nag (Cloud Icon) disappears and reappears because WiFi is still on despite being on Airplane Mode.
So, then I erase User Save Data with both Nintendo Data Management and DevMenu. Uninstalled the game. And reinstalled without any update, system then asks for game update. I install the update and then it crashes on loading.
