Android / Amazon Fire App keeps storing cached ADs, stuffing phone's storage and causing crash


Hey guys,

I'm having a quite big issue with my Android app using IronSource extension.
It is storing cached video ADs on a phone's storage and using more and more phone's storage, longer the app is running, causing the app to crash eventually.
Is there a way to restrict how much GMS2 project can use and store cached files? Or a way to delete them?

Thanks for your help! :)
