Please note the placespotting puzzles:
By changing the licensing model on Google Maps, only 650 placespotting calls (including 200 location searches) per day can be made without any problems. So it can happen that in the course of a day the daily quota is already reached, then there are two possibilities:
1. Just ignore the message and solve the puzzle anyway. In this case, only no street names are displayed, the puzzle can still be solved or
2. Wait until the following day at 09:00 a.m., when the contingent has been deferred and the program works again without restrictions
