Issue with Country Code Selection in Garmin Messenger Android App

After installing the app, I proceeded to the sign-in stage where it required my phone number. However, I faced an issue with the country code selection. The app presents a list of country codes to choose from, but I noticed that the China country code (+86) is not included. This omission prevents me from completing the sign-in process and effectively using the app.

Interestingly, I found that the Apple version of the app does not have this issue and includes the China country code.
