Do you realize how many hundreds or maybe even thousands of apps there are? I would say they check them to some extent, but they are probably pretty busy getting rid of ones that are malicious and/or have illegal content as well as working on their own OS and their channels to have time to extensively check third-party apps for all possibilities. However, I do think they try to work with those app makers to work out issues, but as far as the fixes are concerned, that falls on the third-party app makers.
