Having the same problem. Was at 66% tracker progress and did not receive the achievement after doing World Photographer missions. The issues appears with the achievement not unlocking appears to be with World Photographer mode.
Although there is also an issue with Career Modes Missions completed showing “0” no many how missions have been completed in the statistics section that may be contributing to the problem.
This issue is affecting many, but not all people. Similarly the “5K Fun Run” achievement doesn’t track and unlock for a subset of people as well. All other achievements appear to unlock as they should.
