App Crashing or Won’t Open? iPhone Re-sign Guide (Fix Revoked Apps)

CloneMyApp · Updated Aug 2026 · ~5 min read

A signed multi-open app that suddenly won't open or crashes on launch has usually been "revoked" (the signing expired). Don't worry — a quick re-sign fixes it and your chats stay put.

Why does it get revoked?

Signing certificates have an expiry. When it lapses, or after a major iOS update, the signature becomes invalid and the app stops opening. It's not the app itself breaking.

What to do: one-tap re-sign

Re-signing signs the app for your device again so it works. With CloneMyApp you get a reminder when it's about to expire; one tap re-signs it, usually within minutes, and your chats and account are kept.

How to reduce revokes

  • Before a major iOS update, ask support whether to back up first.
  • Choose a service with "free re-sign" — far more stable than fake apps.
