Google has Abandoned Support and Compatibility for iPhone

Drive has become totally useless on my 7plus. Started having streaming issues about 6 months ago. Most videos won’t play or stop part way through. I struggle to open photos most of the time. I don’t know what happened. Phone has been reset. Completely reset to factory. App has been deleted more than once and reinstalled. Every successive update gets worse and worse.
I really think the reason is competition. Regardless of the numbers of Apple users, Google just doesn’t care as a priority about non-Android phones and making sure compatibility is there. These issues have been going on for so long I honestly feel like Google has just abandoned support for iPhone.
As I was told from one Google employee, Drive is not meant to stream content (even though it’s my own and I PAY for storage). It’s simply meant as cloud storage.
I have gone from limited use to now, after the latest update, not being able to stream any video or even open a photo from my account. This isn’t some third party created app...this is Google. I seriously can’t understand how this is possible.
