According to https://support.garmin.com/en-US/?faq=LR6HR5Xul6A9zoxySC5KM9 the current version of the Cycle Maps is 2021.20. My Edge 1030 plus has 2021.10 installed and Express (version 7.10.0.0) does not show that an update is available.
Anyone who has already had 2021.20 available for them? Or knows when this will be available?
