You can exclude a specific URL from being loaded into the PWA. This way, if visitors access that URL from a mobile browser, they will see the classic mobile version of your site instead of the PWA.
1. Go to the PWA configuration screen from your WordPress dashboard.
2. In the blue Plugin settings box, click the PWA Excludes link.
3. Type or paste the URLs you want to exclude (one per line).
4. Click Save.
