Looks like they're also adding some QoL improvements. From Serebii:
Ahead of the new update coming tomorrow which adds three new areas to the game, some more changes have been detailed for the game Now, when you go to Retry a level after completion, you will get to select the Research Level again so you don't have to exit out in order to select the same stage with a different Research Level You now have the ability to go directly to camp without having any photos assessed If you achieve a LenTalk Mission with one of your photos, they will get flagged as meeting the requirements before you get it assessed You can now directly save images onto your Nintendo Switch directly from the photo editing option
