The tablets don’t talk directly to those services, they only talk to reMarkable’s cloud servers, and those talk to the outside services.

That’s a very good point I never considered.

Thanks for the info on how the USB connection works. It’s close to how I assumed it worked but I wasn’t confident enough to answer!

If you connect the tablet via USB, there’s a toggle in the settings which lets you access the tablet from a web browser. It allows you to copy stuff to and from the tablet.

It works on my work laptop which has the USB ports locked down for data - I can normally plug in the items approved for work like my printer, hearing aid programmers, video otoscope etc but it doesn’t allow me to use non-Bitlockered USB drives. The tablet doesn’t show as a storage device like you’d normally expect and uses some kind of black magic fuckery to transfer data.

You can also use OneDrive to download stuff to the tablet, but I don’t think you can go the other way and upload anything to the cloud. My workaround is to simply email any marked up documents to myself.

If you have got the update, it’s not super obvious how you use the feature initially.

You have to draw a roughly straight line, but instead of lifting the marker you keep it held down. After a half-second or so it will convert to a straight line starting from when you began the line, and you can move the end of the line around for as long as you hold the marker down. Once you lift the marker it will draw the line.

I mention it because I skipped the release notes and was looking everywhere for a new pen or option and couldn’t see it.

Another caveat is that it doesn’t work for all pens - the ballpoint, marker and fineliner work, but the paintbrush and calligraphy pen doesn’t as far as I can tell (not tested the pencils)
