When I look at the Properties of a Photo, it shows as Uygur District, Almaty Region, Kazakhastan.
Photos where taken in Canada, In the phone it shows OK.
Also, if I click on Places, it shows the map of Toronto area (that is OK) but if I click the Locate Me button, it displays San Diego California area.

What is the purpose of the Places button? I thought the it will show areas where photos were taken.

I know what the problem is with Terra Photos Places.
This is the coordinates you are using (Kazakhastan) and it is WRONG:
43°35'53.7"N 79°42'53.9"E
43.598252, 79.714982


It should be (in Canada):
43°35'53.7"N 79°42'53.9"W
43.598252, -79.714982

Please notice it is minus 79 (-79) or West, not East

Can you confirm that you know now that there is a problem?

The way it works now showing my photos somewhere on the other side of the world is not working for me.

Hi, yes I am willing to allow remote assistance.

But the problem is easy to fix. You are using the whole number, assuming all numbers to be positive.
This is the coordinates you are using (Kazakhastan) and it is WRONG:
43°35'53.7"N 79°42'53.9"E
43.598252, 79.714982

It should be (in Canada):
43°35'53.7"N 79°42'53.9"W
43.598252, -79.714982

Please notice it is minus 79 (-79) or West, not East
Maybe most Terra-Master owners are East of Longitude 0 (British Royal Observatory in Greenwich England) in Europe and Asia, and that is why they don't see the problem. We are west of it, therefore Longitude is a negative number or WEST.
The coordinates are in the EXIF and are correct. Terra Photo is using the whole number (79) instead of (-79).
This may help understand:

Way back in 2018 Google Photos (or Google Map) had the same problem as you can see here:
https://support.google.com/photos/threa ... sgid=92523

If you use .Net as a reference:
https://learn.microsoft.com/en-us/windo ... dfrom=MSDN
PropertyTagGpsLatitudeRef
Null-terminated character string that specifies whether the latitude is north or south. N specifies north latitude, and S specifies south latitude.
PropertyTagGpsLongitudeRef
Null-terminated character string that specifies whether the longitude is east or west longitude. E specifies east longitude, and W specifies west longitude.

If Latitude is S multiply Hour by -1
If Longitude is W multiply Hour by -1
Anyplace south of the Equatorial line is S (South Latitude)
Anyplace West of the Greenwich meridian is W (West Longitude)

Canada is Latitude N (North) and Longitude W (West) 46.68562781346285, -76.53958640423782 Positive, Negative
Italy, France, Greece is Latitude N (North) and Longitude E (East) 45.15725514748624, 7.835414894197417 Positive, Positive
Australia is Latitude S (South) and Longitude E (East) -19.219872561239473, 139.14400629025954 Negative, Positive

Hope this help.
