Saving status toast should be shown slower

[markoaamunkajo]

Description:

On sensor settings page when user changes setting it will be synced to cloud with status toast popping up at bottom of the screen.

The first "saving to cloud..." status shows too fast for user to be able to read it Let's make it a little bit slower

Actually toast for "Saving to cloud... Please wait." is showing for indefinite time. Once it's saved or failed toast is replaced by "success" or "fail" message. I can add additional delay, what should it be?

500ms - should be delay
