If the phone or tablet paired with the watch installed the specified, probably not public, version of Garmin Connect - 4.61 (from a popular alternative app store), then the names of settlements that are hundreds of kilometers from the location of the watch and phone are displayed on the Garmin watch dials. In addition, for users of watches with Cyrillic names of settlements, all names of settlements are forced to be displayed only in English.
If you downgrade Garmin Connect to release 4.60 (this version is on Google Play as release), then the problem disappears. The names of the settlements are now displayed correctly. Including support for Cyrillic.
Dear Garmin team, please resolve this error. Otherwise, when your next release of 4.61 appears on GooglePlay, many users will be affected!
