I am using the 1.4.0 version and I’m facing regularly the same issue.
While I am writing an article using the admin panel, after a certain time, I need to relog into Grav admin otherwise I will have an invalid Token and this will make me loosing my article…
2nd time in few days, it is pretty annoying as I can write for 30mn to 1hr in a row.
I’ve just lost one now…
Any upcoming feature to fix this?
