Auto rotation button gone missing

[ReikiWitch70]

Hi everyone.

Yesterday I turned on my Samsung s7 light tablet and found that my auto rotation settings wasn't working. My screen is on wide setting and wouldn't change. So I turned my tablet off and turned it back on, to see if it would reset but instead my auto rotation button had gone. I have tried everything and nothing happening😣 I don't want to reset the tablet because I have a lot of work on it. I noticed this happened after its latest update. Can anyone help
