I often use /tmp to save files I don’t need to keep or to transfer them between applications.
But it seems with snaps this doesn’t work, is there any way to access /tmp?
File dialogs show the contents of /tmp from such applications but I can’t seem to read or write any files in them.
I’m asking this both as a snap developer (where I might create a file in /tmp from a snap to be opened by applications outside the snap) and as a user (where I might create a file in /tmp and want to open it from a snap).
