Welcome to the community.

You've clearly done a thorough job already. Let me highlight a few additional steps from our troubleshooting guidance that may not have been fully covered yet:

1. Isolate whether this is an ISP-level issue
Temporarily bypass the Deco entirely and connect your phone via a hotspot from another device that's directly on your fiber connection, or connect a PC directly to the modem/ONT. If Google Play and YouTube also fail in that scenario, the issue lies upstream with your ISP, not the Deco.

2. Check Parental Controls
In the Deco app, go to the Parental Control section and verify that your Pixel 9 Pro is not accidentally assigned to any profile that could be restricting content or applying time limits.

3. Verify QoS bandwidth settings
Open the Deco app, go to MORE > QoS, and confirm that the Total Bandwidth matches your actual subscribed fiber speed. A mismatch here can throttle specific traffic types unexpectedly.

4. Disable QoS entirely
If QoS is active, try disabling it completely (MORE > QoS > toggle off, or set to Standard with no priority devices and bandwidth set to 1000 Mbps up/down). This would help rule out QoS as the cause.

5. Disable ECO Mode
Go to MORE > ECO Mode and make sure it is disabled, as this can reduce performance in ways that affect specific services.

6. Try different speedtest servers
Run a speed test via https://www.speedtest.net from your Pixel on the Deco network to confirm baseline connectivity is healthy.

Regarding hardware offloading specifically — unfortunately, we don't have information in our knowledgebase covering that setting on the BE63 or its interaction with Android/Google services. Given how targeted the issue is (only Google services affected, only on Wi-Fi), and that you've already ruled out most common causes, this may require deeper investigation by our technical team.

Since you've exhausted the standard troubleshooting steps, if none of the above steps clear up the issue please reply back to this post.
