How to ensure that my Google accounts sync frequently? Since I upgraded my S7 to Nougat I notice that the syncing of my google accounts is particularly slow.

If on a computer I create a calendar event, or I send myself an email, I often do not see that as an Inbox notification, or reflected on my Google Calendar widget, until I actually open either app.

I guess (but I am not sure -- how about push notifications?) that this is related to the Google Account syncing being too slow, see attached below ("Sync Calendar", "Sync Gmail" and "Sync Inbox"), taken on 6/20 8:15am.



The things I already tried:


I do have continuous internet, tried switching between WiFi and 4G
mobile internet, all work. I receive near-real time notifications for e.g. WhatsApp and Slack.
In Settings > Apps > Special Access > Optimize battery usage, I added the below to "not optimized":


Calendar
Calendar storage
Gmail
Google Play services
Inbox

In Settings > Device maintenance > Battery > Unmonitored apps, I added


Calendar
Inbox
You can try to force account sync by manually resetting the time.


On your device, open the Settings app.
On "System", tap Date &amp; time.
DisableDate &amp; auto time and Automatic time zone.
Change the date and time manually to be incorrect.
Tap the Home Screen button.
Reopen the Date &amp; Time settings.
Change the date and time manually to be exact again.
Activate Automatic date &amp; time and Auto time zone.
