Looks like it's a bug in 4.26.0 of Facebook AudienceNetwork SDK. I submitted it to Facebook and got a reply that they are investigating, and taking a lot of time doing so - see https://developers.facebook.com/bugs/213725762497306/

The only work-around for this bug I found was to downgrade to version 4.25.0, but it has its own problems, for example some of the users of my app hit now a bug

IllegalStateException: register failed, the sensor listeners size has exceeded the maximum limit 128

Other developers reported some arithmetic overflow bug with 4.25.0, which I have not seen so far.
