I created deeplink from branch.io dashboard as mentioned here and used the same deeplink in facebook ads.
I am able to get referrer value (utm_source and utm_campaign) when app is installed from the facebook ads preview (shown in facebook app notification) but not in case of live ads (ads shown in user's facebook feed).
In live ads,utm_source and utm_campaign are always not set.
Below is the string that I get from install referrer broadcast when app is installed and opened first time from facebook live ads which has deferred deeplink :
utm_source=(not%20set)&utm_medium=(not%20set)
I am unable to fix this issue, what changes needs to be done?
