Since somewhere in 2020, a lot of people have a problem with installing the LEGO® NEXO KNIGHTS™: MERLOK 2.0 app. With some help from BringMerlok2life, I found a solution to this problem. Check the tutorial video below.
Note: This works only on Android devices and Android device emulators. Not for iOS.
Note: I strongly suggest opening this tutorial on the official YouTube website/app since you can't view the video description nor comments on the embeded video.
