Some of my apps (Pandora, Pokémon go, and Tumblr) are not loading on my Samsung Galaxy S7 when I am on my home wifi. Other apps and roku work just fine. I can load those apps when not on wifi. I tried airplane mode, WiFi on, and it didn't work. I've cleared the cache on these apps, restarted my router, my phone, etc. Nothing works. When I load the app on data and turn it to my home wifi, the apps work for a little bit (few minutes to an hour). I really don't know what else to do. I'm not very tech savvy either. This has been going on for a few days. Also, sometimes my phone won't connect to my home WiFi. I'll click connect, input password and it says it's wrong, when I know for a fact it isn't. After trying for like 30 mins it will connect out of the blue. I'm at my wits end.
