A recent bug in Google Ads is causing frustration among advertisers, as it has started blocking any attempts to edit Performance Max (PMax) asset groups. I’ve personally encountered error messages when trying to update asset groups, making it impossible to save any changes directly in the platform.
Why This Matters to Us. As an advertiser, the freshness and adaptability of our assets are crucial for campaign success. Without the ability to update asset groups, there’s a risk of my campaigns running with outdated content, potentially harming their performance and efficiency.
What I’m Experiencing. Like others, I’ve faced an error message stating, “An error occurred. Please try again later. Value is required,” each time I’ve tried editing any asset group details. This error shows up in the Google Ads UI, stopping me from saving any changes even if all required fields appear to be filled.
Google’s Response. Google acknowledges this issue and is looking into it. However, they haven’t provided a timeline for a fix or any further guidance through their official channels yet.
Temporary Workaround. For now, I’ve found that using the Google Ads Editor allows me to make necessary changes and upload them directly. While this method works, it introduces additional steps that disrupt my usual workflow of managing PMAX via the web interface.

Next Steps for Advertisers. If you’re running Performance Max campaigns like I am, it’s essential to revisit recent changes to ensure they’ve been saved correctly. In the meantime, directing any necessary updates through Ads Editor may be a wise choice until Google resolves the issue.
Looking Ahead. Until Google addresses this glitch, a new level of uncertainty might accompany managing Performance Max campaigns. It’s important for us to double-check our versions and explore alternative workflows.
