Tell me, please, what is the maximum actual size for the mediatopic post format now?
Previously, it was 492*364 (the same is indicated in the documentation), however, I notice that now many communities post in sizes up to 600*400.
There is also your article about extended information about the application in the catalog, called by the info button, it also mentions the format of posting media topics, but the pictures are obviously larger.
