The April 2018 update to AGOL has broken sooooo much of our content. The latest snafu? When our AGOL home page is viewed in a phone, instead of listing the gallery content it lists EVERYTHING. It lists service definitions, logos, feature layers, basemaps, vector tiles...EVERYTHING. It is only supposed to display the content that is specifically assigned to the group whose content is to be displayed. Viewed on a PC or tablet, it is normal. We're discovering this right on the heels of having to rebuild half of our web apps from the ground up because the update broke the search widget in the web-app-builder apps and it wouldn't zoom anymore. Aslo permissions were somehow blown and our public facing apps started prompting for a login The only fix that worked was going from scratch -New web map and app. Absolutely livid with ESRI right now. Test this garbage. We're customers, not guinea pigs.
