Bug: CXP export on iOS shows 0 items (Family subscription)

I'm trying to export my vault data using the Credential Exchange Protocol (CXP) on iOS, but the export consistently shows "Export 0 items" regardless of the destination app.

Setup:
- 1Password with a Family subscription (personal account)
- iPhone running iOS 26.3
- 1Password app is up to date from the App Store

Steps to reproduce:
1. Open 1Password on iPhone
2. Tap the account icon at the top left → Settings
3. Go to Advanced → Start Export
4. Tap Continue on the information screen
5. Select a destination app (tried both Bitwarden and Apple Passwords)
6. First tap on Continue always does nothing - tried this flow multiple times
7. Second tap on Continue shows "Export 0 items”
