Hi @Alexander1881,
It may help to first confirm that you're logged into the Airbnb account associated with the specific guest booking. Sometimes, being signed into multiple accounts can create session conflicts, which might be causing this issue. Logging out and then back in might also refresh the session and clear up any access problems.
If the error persists, clearing your browser's cache or using a different device or browser to leave the review could help resolve any browser-specific issues.
Lastly, if none of these steps work, contacting Airbnb support may be necessary to ensure your account has the correct permissions to leave the review.
I hope this helps.
All the best,
Upfish Management
