I had a same situation with "E/FrameEvents( 4927): updateAcquireFence: Did not find frame." and the counter kept spinning. I have set up the Google API key all as recommended, asking GPT but without luck. The map was present but was grey with Google watermark. And at the end I found out that I didn't enabled Maps SDK for Android and for iOS, it's a stupid mistake but I'm sharing it in case it saves someone time. :)
