After update I can not edit my meta snippet

Hello,

Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.

I am afraid that I cannot reproduce this on my end when using the block editor nor the classic editor.

Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:

Please let us know if you find the culprit.

Only the site admin would know and your users won’t be affected by this troubleshooting.

Looking forward to helping you.

Hi,

If that doesn’t work, we might need to take a closer look at the settings. Please include your WP logins in the designated Sensitive Data section.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
