i just blurred out my contacts names and emails for convenience .
look at it what do you see different? the buttons such as invite, photos, send files is missing; to see them i have to hover my mouse around that area and it'll drop down like its been hiding even though i didn't hide it mind i did blur it but it didn't hide. this is happens when i'm speaking to 1 ONE person and then another person talks to me and the tab bar is seen but the buttons disappear.
