Toy Hub (Test) — internal testing build, not the App Store version.

Installs v3.6.0 (261023177) · tag ota-test-261023177
After installing, Settings shows this same number at the bottom — if it differs, the install did not take.

iOS: must be opened in Safari on a device already registered on the dev team.

Android: a direct download, no sign-in. Once downloaded, open the file to install (needs "install from unknown sources" allowed for your browser/file manager).

What changed in this build is in the admin console, under System → Build History. It is not listed here: this page has no login, because an iOS install fetches the manifest and the IPA with no session.
