Problem with google apps not working with gmscore on Android 6

Android version: 6.0.1
Device: ZTE Blade A506
ROM: 20170907093019763

Build: 335900B0592GEN_TR_A506_V1.0.0B01
ROOT: magisk v12

The device was rooted with magisk v12. google play store apk backup has been taken. google play and google services and google apps were deleted with root authorization.
The gms 223616050 version [v0.2.25.223616] cannot be installed on the device.
I was able to install gms 214816048 [v0.2.24.214816] version. I didn't install fakestore. I installed the google play store apk backup application with normal installation without root permission. I added google account with gmscore from google play store, logged in to my account. And I downloaded google Inc apps. youtube, drive, documents, news applications downloaded and installed. But apps don't see my google account. The gmscore account add page opens again. When I try to log in to the same account again, I get the "already logged in" warning. I am also logged into google in google play store app and connected. But google applications cannot be used because they cannot see the session, they cannot connect to the session. Apps are not working. When I click on the youtube application, I get the error "google play services must be installed" and the application closes.

I go to the accounts section of the device's Settings. I open google accounts. My account seems to be linked. I click and open the account, click the three dots, click remove account! and confirm. I'm removing the account.
Then I open a google application except youtube. I'm logging in to google account with gmscore in the application and adding an account. still the app is not connecting to google account.
This problem only occurs in google apps. For example, my paid pro version apps are registered to my google account. Fake GPS Pro, Swapper Pro, Greenify Donation Package installed. Google play store can identify pro versions of these apps. And I can use the pro versions of the apps. Although the pro versions are also registered to my google play account, the pro versions are working. Gmscore successfully connects these applications with google play.
But the apps of google Inc company in google play store cannot connect to my google play account or google device account. Although the Google partner app is also installed.

I thought the problem might be in the gmscore version, v0.2.23.214816 ; v0.2.21.212158 ; v0.2.20.212158 . And I tried these combinations in order by installing the old versions one by one. I had the problem with older versions as well.

I also deleted google play store and installed fakestore. I downloaded the apps from the aurora store. I had the same problem again. The apps didn't open, I couldn't use them. I tried one by one, repeating the same steps over the old versions of gmscore, and repeated all the combinations. I had the problem again, google apps unavailable.

Then I reinstalled version 214816048. I uninstalled google play store app. I installed the aurora store app instead. I restarted.

I downloaded and installed google apps with Aurora Store anonymous account. I've tried. Again I followed the same steps. I had the problem again.
I signed out of the anonymous account in the Aurora Store account settings. I tried logging into my google account but the app didn't react, didn't log in.
If I could log in, I would use aurora store instead of google play store.

I apologize and ask you to resolve this issue.
I would also like you to contact the aurora store team and ensure that the aurora store is fully compatible with gmscore.

Start by reproducing the account-session problem on Android 6.0.1 with the ZTE Blade A506 and the reported GmsCore versions. Check the device Settings account flow and the Google app login behavior, including YouTube's Play Services error. Done means Google apps recognize the added account and open without reporting that Play Services is missing.
