You're definitely right in that you can't preview the max limitation on the Companion / Web app before completing it. Unfortunately, the app is never accurate with these things and is always a buggy mess and we're constantly being told to always preview on console (as a cross-reference). I don't foresee you'll get your compensation unless this is an issue that has affected thousands. :/
I'm sorry this has happened to you.
Moving forward, do not trust the app unless you are absolutely sure that it is what you want it to be. I don't see EA compensating you for it, but I do think the app description should do a better job than this!
