Got it, thanks!
If you haven't already can you try setting a different DNS on your PS5 to see if that helps? I've seen some cases in the past where changing the DNS can help with similar issues.
To update the DNS follow the steps below:
1. Open up your PS5 Settings
2. Select Network
3. Go to Settings and select Set Up Internet Connection
4. Choose Wi-Fi or LAN Cable depending on what kind of network connection you're using
5. Select DNS
6. Enter 8.8.8.8 as the Primary DNS and 8.8.4.4 as the Secondary DNS. This is the public Google DNS, but if there's a different DNS you would rather use instead that's OK as well.
7. Select Done
Let me know if that helps at all with the lag issues you've been seeing after that. Thanks!
