Fixing YouTube Studio Something went wrong error when changing AdSense 2026

To fix the "Something went wrong" error when changing AdSense in YouTube Studio in 2026, start by clearing your browser cache and cookies or switching to an Incognito window, as this error often stems from session conflicts or expired authentication tokens. Ensure you are logged into the primary owner account of the YouTube channel and that no other Google accounts are active in the same browser session. If the issue persists, verify that your AdSense payment profile is fully completed with an exact match of your legal name and address, as any mismatch can trigger an automated block during the linking process. Additionally, check for browser extensions like ad blockers that may interfere with the redirection script. If the "Change Association" button is missing or greyed out, it may be due to a recent change attempt; you must wait 32 days before the system allows another association update.
