Yes i would expect this as well to just simply click a button to initiate a export of all properties at once but this feature does not exist or we have no control over it. Requesting it will be charged (claiming it takes to much server performance !!!). And for all other regions we would need to get the region administrator request the same. Hence my question if there is a solution you know of to export all current properties and re-import them.
The issue appears to be fixed now and i got everything assigned correctly.
Thank you for your fast and good assistance, always having a good experience here. This is very much appreciated and not standard these days.
