Certain apps won't load on my tablet

[Android Central Question]

I opened my YouTube app only to find that it wouldn't load. The YouTube logo appeared as normal, but the home page just kept loading forever. I then tried to go on chrome, but it wouldn't even open the app when I clicked on the icon. Basically, all of my Google apps won't load, including Google settings, gmail, the Play store, etc. However one of my game apps (Terraria) won't load either. The rest appear fine though. Additionally my tablet has been laggier than usual ever since the problem arose. I've already tried restarting my tablet numerous times, force stopping and clearing the cache and data of the affected apps and of Google Play Services, but to no avail. I've also tried switching my Wi-Fi, but the problem persisted. The only thing I haven't done is perform a factory reset, which I'd rather not do. Any other ideas that might solve this problem? Sorry for the wall of text.

Forgot to mention that I have a Lenovo Tab 2 a10-70F that's running Android 5.0.1

Angry Birds Friends would not load to my Galaxy 8+ after an update. Did all the right fixes-no load. Normally, my mobile data handles everything with ease. So??? Just for the heck of it, l tried using our house WiFi instead of my mobile data. Voila! It loaded. Idk why bc all the other games install, load & play without problem. Whenever l play ABF, however, l now have to switch to WiFi. It works for me... Give it a try.

You're trying to install from the Play Store, or from somewhere else?

@DrMomz, I would always go WiFi when available. But you ARE aware this post was almost 3 years old and the OP hasn't returned since the post was made, right?
