+### Why do I not get prompted to enter an encryption password when exporting?

+Aegis uses the same password you have configured to encrypt your vault as the
+password which is used when exporting and importing your vault; so when prompted,

+        <p>
+            A recent Android Pixel update introduced a bug causing Aegis to sometimes show a black screen after unlocking the vault.
+            We have reported this issue to the Google Issue Tracker (<a href="https://issuetracker.google.com/issues/352963108">link</a>) and
+            are awaiting a response from Google. In the meantime, we have implemented a workaround that eliminates this bug.
