Bug: Sharing opens in last context

[ModischFabrications]

First off: Great app, thanks for sharing! Perfect for my use case, without any ads, payment or bloat.

The app doesn't seem to handle sharing correctly. After selecting the app during the share dialog the app is opening fine, but it's back in it's last state, e.g. showing the last picture I edited manually. This seems to happen from any app, not just the gallery. I would expect the app to start the process with the shared image pre-selected.
I can open and use the app via the launcher and everything works as expected.
