Swipe to Backup and wait during process.

Go to Home screen and continue with next chapter.

Save backup: still under TWRP recovery, connect tablet to PC.

Go to Mount menu and check Data partition is checked and MTB button is on "Disable MTP" state.

8) OBTAIN GOOGLE MOBILE SERVICES (GMS) CERTIFICATION

Google now restricts Google Play and Google apps access to certificated devices. Since you have a custom ROM, you are banned.

We now need to subscribe for the Google Play Certification.

Download Device ID (by Evozi) app from Play Store.

Launch app.

Tap on the Google Service Framework (GSF) line, then tap on the COPY button.

In your Android webbrowser, go to: https://www.google.com/android/uncertified/

Connect to Google using your Google/Android account.

In the input field of the page, paste the 16 digits code.

Click on the Save button, a success message confirms your device is Certified.

Then go to Settings > Apps > Google Play Store > Storage > Clear storage

Do I need to re-certify it ?

"Your device’s GSF ID is reset every time your device is factory reset (or when you wipe the GSF app itself) since it is stored in your data partition, so you must re-register your GSF ID every time you perform either of these actions."
