App Store is taking too much time to load

My App Store most of the time takes too much time to load when I search for an app. I’m using iPhone 11 Pro mostly on Wi-Fi which has pretty good speed. I can watch YouTube videos at their highest resolution but at the same time the App Store doesn’t load and asks me to retry. I’m pretty sure now that it’s not my Wi-Fi problem. Sometimes I literally need to restart my iPhone for the App Store to work properly that too only for some time. Please help me resolve this problem. It sometimes really wastes my time when I need it the most!
