It's not uncommon for Play Services updates to roll out at different times for different devices, carriers, or regions. In some cases, it may take a few days or even weeks for the update to become available for your specific device.
One thing you can try is clearing the cache and data for the Google Play Services app. This can sometimes help force an update to appear. To do this, go to your device's Settings app, then to Apps & notifications > See all apps > Google Play Services > Storage & cache. From there, you can clear the cache and data for the app.
Another option is to manually install the latest version of Play Services from an APK file. However, this can be risky and may cause issues with your device if you're not familiar with the process. It's recommended to only attempt this if you have experience with installing APK files and understand the risks involved.
If neither of these options work, you may need to wait for the update to become available for your specific device and region. In the meantime, you can check for updates manually by going to your device's Settings app, then to System > Advanced > System update. If an update is available, it should appear here for you to download and install.
Hope it helps!
