missing conversionEnvelope on ios conversions for Verifiable Ad Conversion

[iambrianfung]

Verifiable Ad Conversions do not seem to be working consistently on iOS.

Originally thought to be due to slow upgrades but example A. is a fresh campaign that only started after ios was supposed to be supported.

All ios conversions are missing conversion envelope
Example A.

Some ios conversions have conversionEnvelope
Example B.
Use link from above but replace WHERE clause with
WHERE ads_aurora.campaign_redshift_staging.campaign_id in ('04d01606-3bf2-41d9-afa2-54408159ed43', '1056f376-67d3-49dd-a255-f0854f1c4907')
