I can t download on my tab while the hotspot is on and my s4 the only o

[AC Question]

While using my android tab as a hotspot and only my s4 as the only connected device, the playstore only downloads apps on the s4 and not responding on the tab. Even after switching the hot spot of the app doesn't want to download, it's only scrolling like it wants to but even after an hour nothing is happening .
