My card does not show my changes
Wait for the save. The badge at the top of the editor must read "Saved". If a pill at the bottom of the screen says "Saving", the change is still being written.
Force a reload. Straby caches its own files so it opens on a bad connection. Cmd+Shift+R on a Mac, Ctrl+F5 on Windows, or close and reopen the installed app.
Check the item is on. Each item has a switch, and a scheduled item is hidden outside its window.
Check you are editing the right card. With several cards, it happens more than you would think.
In a team, a locked element is set by your leader on the team template: your change was refused, with a message saying so.
Still stale after a forced reload? Write to us and say which item.
