Maybe this bug occurs when more than one ad type is used, not only rewarded video. If somebody can do further tests will be great.

Compiled against current masteer af9c58e , I havent encountered this issue so far.
I'm using banner, interstitial and rewarded video ads at different stages of a game... not using them at once...

iOS 12.4.1
Godot 3.1.1

Well unfortunately I did manage to replicate this after closing interstitial ad...
I dont get why after closing interstitial / rewarded ads, the banner ad is explicitly enabled and showed...

I'm not sure about this but it is probably the source of issues as after an interstitial is closed I call loadIntersitial which might not finish loading in time.
Instead, implementation of proper ad loading & showing/hiding should be left on the end user.
