Why does this happen?

[Nico65]

For the past week or so when I check my email if I swipe to the right I get the following:

[Move - Snooze - Read - Reply]

However, it occurs sporadically. Once I close my mail and then reopen it, the above will have disappeared. This is one of the features that I've seen in videos about Oreo. Any guesses why it appears and disappears?

I am using Samsung, S8, gmail

What device do you have? Which email app are you using?

Have you tried a cache clear for Gmail in settings, apps?
