Using GameSparks SDK with Unity 2019.3

Hiya,

I haven't been able to post on GameSparks forums for the last 12-ish months and neither have they replied to my numerous emails. I'm actually kind of wondering if they are on life support or what, but that's beside the point here.

I'm trying to update a 5yo in-production game to Unity 2019.3, which has dropped support for
Scripting Runtime Version.NET 3.5 Equivalent. GameSparks apparently relies on that and now throws an error at compile time (there is a version check using #defines).

It is possible to comment out the check in code and it looks like GameSparks still works as expected but I'm sure there is a reason it was there in the first place. To be noted that there has not been any official SDK updates since June 2018 (version 5.6.5.214).

So does anyone has experience with GameSparks 5.6.5.214 with Unity 2019.3 in production? Does it work fine on Android/iOS/Standalone?

Cheers,
Alain-Daniel
