Why is there no synchronization in OneNote on PC and phone?

Question

OneNote

I put it on the PC and on the OneNote phone, logged in under the account there and there.
I need all entries in OneNote on my computer to be available on my phone.
If I add entries on the PC, then they are not visible on the phone!
And are there any free alternatives to OneNote that evernote doesn't offer.

Answer 1

Is the required book open on the phone? Previously, "by default" the application on the phone created a new book "personal notebook", and it was necessary to open the desired one with pens.
And at the first start, you have to wait until everything is synchronized, so if the Internet is weak, you will have to wait a long time.
Basically, try again. I have 10 zap.books, 5 devices, there are no problems with synchronization.
