Can't find dark theme...

[Kurosaki_kun]

I can't access the dark theme option in Gmail or the Google app. Everything I've read suggests it's accessible via the system settings app in Android 10, or on a per app setting on pre Android 10 devices. With further research, I also discovered the dark theme option in Gmail has a tendency to disappear for some users, and I've followed the the steps outlined in various forums and blogs to get it back. The weird thing is I've never even seen a dark theme option in Gmail, I was led to believe it was only available in Android 10 until I did some digging a few weeks ago. Furthermore, I got a "new" phone recently and the first time I started Gmail, I checked the General settings and no Theme options.

I'm currently running Oreo and I have dark theme in the following Google apps:
--Calendar
--Chrome
--Drive
--Docs
--Play Store
--Sheets
--YouTube

No dark theme:
--Gmail
--Google
--Maps

So what am I missing?

P.S. I'm asking this here because I've reported this problem to Google several times and no one has ever got back to me.

I checked my Lenovo Tab 4 8" which is running Oreo, and Gmail, Maps, and the main Google app on that tablet do not have a Dark Theme either. It seems that certain apps are more dependent than others on the Android version for Dark Theme.

Thank you for the feedback. Gahd, the lack of consistency is so frustrating.
