If type inferencing is the problem, one thing you can do is use RxKotlin

implementation "io.reactivex.rxjava2:rxkotlin:$rxKotlinVersion"

RxKotlin specifically provides SAM helpers to help mitigate the issues with type inferencing issues.

In which case,

Singles.zip(..., ...)

would be able to work just fine without any ambiguity. Notice I am using Singles and not Single
