It probably installed an update previously but O+ had not been opened since because, well, I have no need to actually open O+ - I've got it set and let it do its thing lol.
And the number of items is hugely different from the previous v17 Dev build.
From 37 items to 309 items in the folder for a portable version. Including lots of translation folders.
I opened O+ and it said "congratulations, you're on 1.92.728xxx.
Then, a few seconds later it says "an update is ready to install - and proceeded to install this build.
It's actually curious, as new MX generations are usually 2-3 years after the current gen, but it's been longer from the MX Master 3 to the (soon to be unveiled) MX Master 4.
The MX Master 3 was released in 2019, but the 3S is newer, so it does fall within the range of the normal timeline. And...
Checked my Options for updates and it found it right away.
I'm just ready for the MX Master 4 to be released. The left mouse button on my MX Master 3S is having issues, and the MX Master 3 for business does not have the Extended DPI sensor range that the 3S does.
It's almost as if they do not want you to download the (numerically) newer package.
If you click the link in the yellow warning, it takes you to the view that @asturias7 describes lol.
Pro Pro (?) tip:
Make directory that you use only to make the UUPDUMP .ISO (I called mine UUPDUMP, and put it in my \Downloads folder). Then exclude that folder from your AV autoscan (In Defender, set it as a folder exclusion).
I keep the folder even if it is empty, so I can always use it...

RE: diff port working - check Device Manager to see if there are any issues with any of your USB devices / hubs. Also, does anything else work in the USB port that the phone doesn't work in?
