Marketplace shows B-0010 error on Switch despite having internet

For some reason, the Marketplace on the Switch won’t load with error code B-0010. This has gone on for some days. I have tried restarting the game, have internet and the Marketplace still does not want to load in most cases. No matter how long I wait in game, the Marketplace cannot load on Switch… (It works perfectly fine on iOS, but not Switch due to an error code B-0010.)

Here was the error message I got out of B-0010:

“It’s taking longer than expected to load the Marketplace. Please wait and we’ll get you in soon.”
