GPS Smart Remote question

I had postponed buying the GPS Smart Remote in the hope that the Type-C usb connector would appear.

Unfortunately no news yet.

Because it is inconvenient to take photos without a remote, I am still considering buying the current GPS Smart Remote.

However, there is one thing I am concerned about.

Unable to update remote control with Android 10 system.

I do not have a device with an older android version. Updating GPS Smart Remote is not possible for me.

Is this a problem? What exactly is that updating necessary for?

I like to travel, does this mean that GPS fix is difficult in other parts of the world?

What should I do?

Wait for the new GPS Smart Remote?

Difficult decission, because I do not know how long it takes before the new one is available.
