Hey @developerfred seems the PR is mixing others commits not related to the task, can you rebase and just keep your commits?

[octavioamu]

My recommendation is to cherrypick your commits into a new PR this one is mixing other people commits since the beginning, not sure what happened here.

[PixelantDesign]

Hey @developerfred thanks for all of the great work! @androolloyd will bring it in to wrap up the rest for a launch next week. Thank you! I'll pay out for the work.

PR looks good - just needs a bit of cleanup so the style is on point and the migrations are clean. Please make these fixes and we'll get it in the next deploy 👍
