I have one long custom created image course , adding new words regularly. Sometimes, I want to add second or third image to an existing word. That worked always well. Just today, it stopped working. After I attempted to add an image to an existing word-image couple, it throws this error: “An error occurred (InvalidIdentityToken) when calling the AssumeRoleWithWebIdentity operation: Couldn’t retrieve verification key from your identity provider, please reference AssumeRoleWithWebIdentity documentation for requirements”.
Using a standard office PC (HP Compaq) and tried latest Edge and latest Chrome, both throw the error.
