On SNI it came up that admins that have other roles (member) and have the member role assigned first are not able to access the Page Builder button and tools. This must be new with an update as this was presented as a bug only in November of 2020. Regular admin users (e,g, Mm staff) can access the tools as usual. Changing the order of the roles fixed this issue. Aaron is to file a bug report with Jupiter and/or Page Builder.
