Any solution to this? It's started happening to me with my Edge 830 just this last week or so, with a Google Pixel.
I have the same problem. Edge 1030. Samsung Galxy S8. Both devices are in danish language.
Sorry, thought I'd posted this before...
What's reliably worked for my Edge 830 the several times this has come back, is this:
Change the Garmin's language to something other than English, eg
I am in the US using English, using the 1030 with Samsung S10e. It is interesting that it worked fine for the first couple of months, then the language issue suddenly appeared about two months ago. Apparently this issue is been going on for a couple of years on devices other than the 1030. One would think that Garmin would have had a fix for this by now if they cared.
I had the same problem with my Edge 530 recently. I contacted Garmin who said that it was not a common problem and they didn't have a fix for it. Apparently they are currently looking into the issue. I previously tried changing the language to French and then back to English, which worked for a few months. This time I tried adjusting the auto pause settings on the device. I previously had it set to pause at a set speed. After adjusting this setting to the pause when stopped option I have not had any error notifications. Hopefully that will be the end of it. I really like the 530 as a device, but the Garmin software continues to have frustrating bugs.
Glad you posted this. I experienced the same issue. I'm on an edge 530, Pixel 3, and everything is in English. I haven't had any issues on any rides until I changed the "auto pause below a specific speed" option. There had to be some software bug in there when that setting is used that's causing this.
I'll disable that setting and see if things get better.
