My Fenix 6 Pro does not update my Maps

No, Garmin Express is the only way to update TopoActive maps. Beta program is only for firmware, not for maps. What do you mean by 'not possible '? What exactly is not working?

TopoActive Europe 2021.10 is the latest version available by the way.  2022.10 was only available for a short time and was then pulled again. It seems like there were some problems with this version. 

Hello! How can I downgrade the TopoActive Europe 2022.10 to TopoActive Europe 2021.10? Because I have some problems with these map. 

Thank you!

Just out of curiosity: what are the problems with the 2022.10 map?

As for the downgrade, there is no official way. You could try to reinstall the TopoActive map via Garmin Express. Since 2022.10 is not available anymore, it might reinstall 2021.10.

The problem is, in my case, I can't see the hiking trails on the map. And this happened after the update.

Maybe it's something from configuration, but all what I do it was the update by Garmin Express.

Maybe that's one reason why it was pulled back.

According this page support.garmin.com/.../

topo map version is 2022.20, for some reason it still is not available. At #elsewhere it was said that there are some problems with it and should (I repeat, "should") be available in a few weeks. Naturally that depends of how it can be repaired. So nothing carved in to the stone still....
