We've released several bugfixes and minor updates since this request.
Our Unreal Blueprint sdk (https://github.com/PlayFab/UnrealBlueprintSDK) is tested for both 4.9 and 4.11, specifically using our ExampleProjects released with the sdk.

Among this testing, we've verified that Login/Registration, CloudScript, and Leaderboards are verified working, either with examples published with the SDK or, in the case of Leaderboards, an example that mirrors the published ones.

And additionally, we've verified that android builds for this sdk work as well, with the same testing.

Please feel free to contact us if you find any additional problems.

So that everyone has the info we've already discussed via email:

We haven't fully tested our Unreal SDKs with their 4.11 yet, so it's possible there is an issue. If you can reproduce this in 4.9, that would be good to know. In the meantime, I've asked our tools team to investigate this issue and respond.

Is this crash in windows or on a phone device (please specify)?
