my links won't open in apps, it sends me to app store instead

hi, I'm using an iphone xr on ios 15.7.1 and I have had this frustrating problem for a while. when I click on a link, for example a google maps link, this link sends me to app store to the google maps page. when I press open it sends me to the home page on the app but not the location as if I didn't click on the link a few seconds ago. or when I click on an amazon product link it sends me to app store amazon downloading page but I had downloaded the app already and when I open amazon all I can see is the homepage, not the product that the link refered to. I didn't have this probelem before, it's kinda new but definitely I have it for more than a month. I don't want my stupid phone to use the link on safari either, I want to use the app that I had downloaded already WITHOUT being sent to app store. it's driving me insane and I had this problem for like 2 months or so. how do I fix it? please don't tell me to restart my phone I need an actual solution otherwise I'll switch to an android I'm this close to throwing it away..
