Good day @Kate

We reviewed and completed the post-installation steps in the above instance and it fixed the issue.

You can always request the upgrade/post-install here as it is a free service and we will take care of it.

Please let us know if we can be of any further assistance.

Last time you sent me instructions to do this myself, and I cot to the Standard Object permissions, but it wouldn't let me check the boxes, such as "Campaigns." I tried to skip and go to the next step, but couldn't find the "object settings."
