Long story short. I'm getting an existing quiz app customised. Its being created on a dual platform so its available on android and IOS. It will have an admin panel. Once its complete, how hard will it be to upkeep with no coding knowledge? Will it develop issues every time a new version of android is released? Or will it be quite easy to hire someone to come make small tweaks to the code? Again, I know nothing about coding at all. Is this a bad venture without that knowledge, or will it be ok for a quiz app if I'm rarely adding new features? As I imagine a quiz app isn't too complex for a developer?
Yes, you MAY have issues when iOS and Android are upgraded but not with every upgrade. Without seeing the code, it’s impossible to predict how often but hopefully your developer is aware of your concerns.
