Bests & Worsts Reviews from Amazon

Hi!! I have a Amazon tablet and I use it on browser but its so far amazing. I get notifications but it doesnt show on my notifications bar?? I rated it 4/5 because every time I did a voice call, and I try to turn on my microphone, the page starts glitching and then it says "page not found" and I gotta reload it, I dont know if this happens to me, but I cant seem to work my microphone either.. Maybe its just cause I'm on tablet but I dont know lol -Ella🌹
