On Android, I can use the Android share function to share content to Obsidian-- excellent! (This is key to part of my current workflow). Unfortunately, when it gets to Obsidian, I’m asked only if I want to add the content to the (attachments) directory or not, and then I’m asked if I want to create a link to the new content-- except it offers to insert the link in whatever the last note I might have had open was.
Most simply, when items are Shared to Obsidian, ask the same confirming question about bringing in the resource, but THEN ask if I’d like to insert a link in either the current note, or a whole new note.
I’ve only done this a few times, but my workaround is to go into Obsidian first, then open a new blank note, then go back to the providing application and share the intended content to Obsidian.
