I’m seeing the same issue here.
Started on March 10, 2026, and it seems to affect all developer-signed apps on physical devices. I’ve reproduced it across multiple apps and devices after trying the usual fixes.
On-device, my message is:
Unable to Verify App
An internet connection is required to verify the trust of the developer cert
It looks like an Apple-side verification outage affecting dev app trust and certs.
Would be great to get confirmation from Apple and an ETA for resolution.
