I don't think it was that fast. According to the included readme file, FW ver. 1.0.1 beta was built last November 23, 2018, meaning they were holding off this update for a month (of course, with the exception of those with stainless steel models, which came pre-installed with 1.0.1 beta). If this post by Ken is to be believed, they're testing out LDAC before they made the update available to everyone. Well, at least they're making sure LDAC is working properly before they released the update file. So bi-directional Bluetooth is now working properly, and now streams aptX and LDAC, not just SBC? Looks like the AP80 users who bought it for LDAC finally got their money's worth. Hiby Link album art display still doesn't work properly, though; it doesn't display the album art on the HibyMusic app on Android (dunno on iOS version). Still looking forward to further improvements (especially UI tweaks like ticker text scrolling, etc.) on a future firmware update. I hope Hidizs wouldn't stop there.
