Answer
There is a known issue within the Microsoft Outlook iOS app that can intermittently cause errors when sharing workflow PDFs from ANVL. Adjusting the app’s display settings resolves the issue in most cases.
Change the Outlook app theme settings to Light mode to resolve the sharing error.
Steps
Open the Outlook app on your iPhone.
Tap your Profile icon.
Tap the Settings icon near the bottom of the screen.
Select General.
Tap Display & Appearance.
Set:
Theme to Light
Icon to Dark
Tap Save.
After updating these settings, return to ANVL and attempt to share the workflow again.
Additional Details
If the problem persists, ensure both Outlook and iOS are updated to the latest version.
As a workaround, you may also use the iOS Mail app to share the workflow.
