You are left with a screen that shows the photo that you have taken. There is nothing "tappable" and you can't do anything to add the photo to Fossify SMS Messenger.
If I select the back button, I am taken back to the messenger app, but the photo is not attached.
Expected behavior
I would expect that the photo would be added to my message.
It's a bug in your camera app, not in Fossify Messages. When a photo is taken, your camera app should display two buttons - accept and cancel. You should raise this problem to LineageOS.

Additional information
I do know that that Lineage 20 has replaced the old stock camera app with a new camera app. I don't know if this is relevant, or not.
