House numbers and houses disappeared from bing maps, what should I do?

Question

Microsoft

Hello, I made a project for a network map provider with the ability to add subscribers to the map.
The project worked for a long time and perfectly, but in the last two months they began to notice that the house numbers were disappearing, and after NG even the houses were not on the map.
Bing was chosen due to the fact that in other maps the city was like a desert binged.it/1xN6Lpk
now Yandex has drawn more or less detail here.

1. Now the question is, what can you say about this, is it worth waiting for a miracle or running away to Yandex?
   
2. The coordinates of the points are stored in the database in the form of latitude and longitude, will it be on the maps from Yandex or will it have to be overlaid on a new one?
