Many users are experiencing issues with the Sports from Google in Now Bar.
Additionally you can check Notification Categories and enable Sports Toggle
You need to follow the following steps to make sure it works smoothly:
First of all update the Google App to it's latest version - 16.27.69.ve.arm64
1. Go to Settings > Lock Screen and AOD > Now Bar.
2. Turn ON the toggle for Sports for Google.
3. Click on Sports from Google
Click on Sports from Google
3 Options to check
4. Here you need to do 3 settings.
Firstly click on Personalise Search and make sure it's turned ON. Also check whether Sports and your favorite teams, leagues are in the Following section and not in "Not Interested".
Now, go to Web & App activity and turn it ON.
Then go to Sports from Google settings and follow your favourite teams and leagues.
5. After all this open the Google App and click on the top right profile icon.
Click on that profile icon
Then click on Settings.
Click on Notifications
Make sure Sports Toggle is ON
Here also check out Your Topics to ensure you've followed Sports teams and leagues.
Now Go to Settings > Notifications > Google
Make sure that Show Contents on Lock Screen is ON.
Make sure you have latest version of Google.
If Google App is not updated,
THIS FEATURE WILL NOT WORK.
If you have updated recently, wait for 24 hours or more until it starts working. Mine started working in 18 hours.
If the feature still doesn't work.
Turn off Notifications for Google, uninstall the updates and again update the app. Enable Notifications and repeat the entire process.
I hope this helps you. If it does, I'll appreciate if you could like my post as it took my efforts. 😊
Still not working properly.
