We bought the agency plan, but it seems your support is taking a very long time to respond.  We even emailed in the questions. If this is the normal level of support we would like a refund.  We have many issues with Pagebuilder pro.  Found many bugs.  We have deadlines and it seems we are beta testing your new build Joomla 4. 
We have used on Joomla 3 and didn't have as many issues.  Joomla 4 has been a different story.  No point in developing on Joomla 3 since it is EOL and we don't want to rebuild in August.
