JWT Error in Page builder

What is the hotfix applied to your projects? Does the hotfix version applied on admin app matches the version of the Kentico NuGet packages on the live site app? Please, check also the following:

• Live site runs on HTTPS (the live site presentation URL uses HTTPS): it looks like your Live site already runs on HTTPS

• SameSite mode is configured correctly

• Browser does not block 3rd-party cookies

• If you are using a self-signed certificate for the live site in the dev environment - you need to accept this certificate in your browser and reload the administration interface

I am trying to use hotfix 13.0.82. This is after successfully upgrading from Kentico 12 SP to Kentico 13. Just noticed there is now a .84. Should I upgrade that that and try again?

Here is the full error, could our tokens from the live site be missing something?

Global Exception caught

Try reloading the administration interface. The user was not found in the JWT token, nor in the current virtual context URL.

Could you please confirm that your site runs on HTTPS as well as the admin app, SameSite is configured, SSL cert is trusted? Have you tried checking other threads on this error and the suggestions there?

Both running on https, Same Site is configured, SSL certs are trusted and performed all the steps in that thread.

Are you using any custom CSP headers set or any other customization in the web.config file? How is your preview mode support implemented and configured?

Nothing changed between 13.0.82 and 13.0.84 but the preview mode worked in 82 but not 84.
