It does, but the whole point of “upgrading” from my custom build QMK hardware was in part not having to spend as much time building custom firmware just to configure macros and key mappings, which is what led me to buying from Keychron as I thought that would become easier by simply using their Launcher. Having read https://www.keychron.com/blogs/archived/advantages-of-the-keychron-launcher-web-app I thought I was getting a product that had an always-available Launcher but that’s just a lie as it requires internet connection to work. I had (wrongly) assumed it was something like a PWA that is able to be run offline.
