Hi All,
I am just suffering from this issue.
The custom ribbon button is shown in traditional CRM website.
While it is always not shown in Service Hub.
Furthermore, it looks Hub is one version behind/delay from the traditional CRM website.
I can add extra dummy button 1, publish. It shows in website, not in hub.
add extra dummy button 2, publish. Both show in website, But only button 1 shows in hub.
remove button 2, publish. Only button 1 in website. But both show in hub.
I feel so painful. :(
Regards,
Zhenyu
