Google Calendar wont sync between phones

[pizza_pablo]

I switched back to the S9 from Note 9, today and realized that recently added calendar events had not synced.
I've tried all of the steps in search results, like these,

with no joy. I don't have access to wifi, at work, but I do have both phones with me.

1. Make sure that both phones are on the same Google account (or that you have the calendars of both accounts synced to each other).

2. Make sure Google Calendar Sync is enabled on both phones. (And don't have both of they syncing at the same time - enable airplane mode on one of them, then check the other one. Enable airplane mode on the first one first, then disable it on the second one. Two phones fighting the site to sync at the same time rarely works.)

3. Go to Google Calendar and see what's on the actual calendar. (The app just shows what's at the site. If you turned calendar sync off at some point, it was no longer syncing to the site.)

I know you have plenty of experience, but just to be sure -- are those events that aren't syncing actually saved to the Samsung account rather than the Google account?

1. Yes
2 & 3 I'll give a whirl.
Thank you!

ETA, I believe you have found the problem. At the link you posted in #3, the recent events are not there. It looks just like the S9's Google calendar app. However, calendar sync, in my Google account, on the Note 9 was definitely on. Investigating...

Flattery, sir, will get you everywhere!
The Google calendar app, on the usually used Note 9 has the most recent events.
Thank you!

Ok, but on a non-Pixel phone, the Google Calendar app may still let you create an event that is saved to the Samsung account, not the Google account. Can you select one of those events that aren't syncing and look at its details so you can confirm it's saved to a Google calendar account, and not a Samsung calendar account?

I fired up the Note 9 and its calendars now look like the S9.
I believe what may have happened is that I had both phones connected to the internet, last night, while switching from Note 9 to S9. I noticed the calendar discrepancy, then and tried to sync the Note 9 and then the S9.
Likely, neither was syncing, because both were connected. After turning off the Note 9, the S9 calendar became "master" and synced its info.
I guess time will tell how many of those events I miss. 8^))
Lesson learned...the hard way, as usual.

Thank you both for your help that has led to the answer!
