Proposal

Please re-state the problem that we are trying to solve in this issue.

App crashes when close pdf attachment while it is loading

What is the root cause of that problem?

This came from version bump of react-native-pdf (6.7.3 -> 6.7.4)

What changes do you think we should make in order to solve the problem?

While waiting for upstream fix, revert back to previous version (6.7.3)
