On opening WeekPlan this morning I had all my data (basically all of it pushed forward from previous weeks), but after a cache clear I logged in using Google TPA and everything was gone except for my Parking Lot, for both of my teams. I tried signing in and out again, clearing the cache etc. but it didn't change anything.
Again, the data (other than calendar events) was created some time ago and shifted forward, so maybe it's somehow lost in the past? But it's all gone now.
Thanks for the help,
