New Instinct 2x Solar software version 2.06 with no update available

I've bought a new Garmin Instinct 2X Solar from Garmin and it is on 2.06 software version. All the settings on both the iOS Connect app and the watch are set to auto-update, and but no update in the last 3 days.

I don't own a PC/Mac, so Garmin Express is not an option to attempt solve this. Is there anything I can try to solve this issue?

I've read https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/instinct-2-series/332711/garmin-instinct-2x-solar-not-updating-firmware but I've already been waiting a few days, which seems quite a long time for a simple software update.

Also, what's the latest version of the software? If latest version is 12.26 as per forums.garmin.com/.../instinct-2x-system-software-12-26, I feel I'm missing a lot of bugfixes? Or is it Solar latest 3.11 and non-solar latest 12.26?

Thanks in advance!
