Given Dark Mode can really enhance battery life, I'm keen to implement it.
Although all my other IOS/IPADOS 13.3 Apps seem to respect the "System Preferences" > "Display & Brightness" > "Appearance" > "Dark", I noticed gMail didn't for some reason.
Google offered this guidance for configuring Dark Mode:
For iOS 13:
- On your iPhone or iPad, open the Gmail app
- In the top left, tap Menu Menu and then Settings.
- Tap Theme.
- Choose Light, Dark or System default.
Since the menu item "Theme" was missing in my gMail settings, I gave up trying to configure Dark Mode- wasn't possible to follow the instructions to achieve a correct result.
My gMail settings look as follows:
By chance I noticed my Wife was using Dark Mode in gMail. Given we have the same iPad Pros (2019 12.9"), I decided to try to implement Dark Mode again.
Doing some comparative analysis, I investigated how our iPad configurations varied.
Below are my Wife's gMail settings. When you compare the below graphic of her correct settings with mine in the previous graphic, remark (2) things:
There is now a menu item titled "Theme" which is not present in my settings
Version Number: Both the Broken AND Working Dark Modes use same gMail version
How else did the two iPads vary?
My iPad uses both gSuite and a personal gMail accounts
My Wife's iPad only has a personal gMail account.
Remarking this difference, I made the following changes to my iPad to mirror the working iPad (my Wife's):
Deleted the gSuite gMail account to exclude possibility there was a Domain permissions issue. This did not resolve the broken Dark Mode issue
Deleted and reinstalled gMail itself. This too failed to resolve the fault
So both iPad Pro's use the same versions of gMail, but the iPad with working Dark Mode HAS the "Theme" menu in settings, the other with broken Dark Mode does NOT.
