I am not able to see my Android application in Share menu list while sharing pdf from adobe 18.3 version application

I am not able to see my Android application in Share menu list while sharing pdf from Adobe 18.3 version application but below versions of Adobe app, I am able to see my app in Share menu.

i placed the intentFilter in activity as follows
[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] { "android.intent.category.DEFAULT" }, DataMimeType = "application/pdf")]

Do I need to change in my Android to make it work? any ideas?

Please help me resolve the issue

Thank you,

Babu
