Hi Andrew,
I already upvoted this request. However, in my case, the 90 seconds timeout is not the issue as my function takes roughly 40 seconds to execute. I can run the function with no limitations from the server and the iOS App (realm-cocoa).
I guess the problem lies either within the realm-java sdk or on my end somewhere. Would be nice if someone could try to reproduce the error by calling a function that takes longer than 10 seconds with realm-java.
