Changes not being saved/sent to the server.

So I can move tokens, assign them thewir characters, set their hp, all that good stuff. However my players don't see any of those chnages. If I refresh the page I find that all my chnages have been erased and the tokens are where I left them, characters unnasigned.  It seems my changes are being kept locally and not being sent out? When I refresh my players can then see what I do but after a while it happens again. During one 5 hour game it happened 6 times which can be very frustrating. ;-( Any ideas why this is happening? I tend to have a good connection so unsure why this occurs.

I had a similar thing happen. I am running Tomb of Annihilation (I own the book so I am not using the built in stuff in roll20) and I spent ~ 2 hours a few weeks ago getting some areas set up. When I logged in today to do more almost everything I had done was gone and had to be redone. It seems like the first 15-30 min of work I did was saved, but nothing after that.

Oh gods yes! I've had that happen aswell but I never connected it to this issue! Yeah I've had it a couple times were I swore I had prepped the next session but nothing or half of what I had had remained.
