Show me this long message

This was reported before. Your Windows computer the language has to be set to English.

If that isn’t it let me know it may be you have to update to 1.5.7 but I think it is the Windows language.

no , i try to change the window language to english , no thing new

Here is what solved it for others

problem solved
The following should be controlled
1- The language and region must be English
2- The Regional Format same as regional (English)
3- The time of the computer must be the same as the time of the Galaxy watch.

This is a bug and has been reported to the WFS team.
