Muse app fails after a new phone while the web version works: a troubleshooting checklist
After setting up a new phone, a user can no longer use the Muse app past login, though the web version works fine on the same phone and on desktop, even after several reinstalls. Since the account works, the fault is likely app-side: iOS and app updates, re-signing into the Meta account, and VPN or custom DNS settings are the first things to rule out.
