Dissapearing Journal Quests | iOS

I've noticed an issue with journal entries disappearing after completion but before rewards are collected.

Couple of details:
iOS - 12.4.1
Game version 1.35

I've some repro steps. After completing a quest you receive a 'journal updated' notification. Should you click immediately on the journal '!' the corresponding entry will have vanished. However if you move a step before checking the journal icon '!' will pulse and the quest can be safely accessed. I've lost a couple of quests to this (Introductions) before catching on.

Hope this helps
