Have been using firebase, but the tracking is really poor and in iOS the re-direction is poor, plus deferred deeplinking isn’t working as expected.
I’m evaluating Branch and Apssflyer, is there some other provider who I should evaluate?
Deeplinking is complex. More often than not, it's an engineering issue in projects rather than a product issue.
There's not much that happens on Firebase's end to initiate or redirect deep links.
Deeplinking should be engineered and those SDK’s provide tracking functionality only. We had appsflyer and it was plug and play with our existing deeplinking system which was well engineered earlier
Appsflyer mostly has the same issues.
