Despite Power Apps supporting SharePoint Lists as a primary data source, after all these years, it still doesn't natively support 'Choice' columns with multiple selection checkboxes. Even years ago, a Power Apps Team Member blogged about it confirming the lack of support and suggesting an annoying workaround, when every other Microsoft platform already natively supports it. There hasn't been any updates on it in the Ideas forum, nor anything in the Power Apps Roadmap about it either. I've gotten it to work with a wonderful but unnecessary poor coding workarounds, but it really should be as easy as asking a combobox.
Can someone please confirm the status update on native multi-select checkboxes and combo boxes with checkboxes in them?
