Tapping 'home' too fast triggers error in local save #1745

Open fwild opened 5 months ago

fwild commented 5 months ago

The following was flagged during my testing activity. It can be reproduced by:

  1. add new activity
  2. add three steps
  3. add 3D model of apple to one step and
  4. quickly tap home, while it still is saving the 3D model: the two save processes are interfering?
