Thank you, dear @Verona, for your input.

May I ask you again because you were also very helpful and you are always doing a lot of tests 
So when we follow the recommendation by the Dev’s, I guess the settings should be like this (so the option “use only API to save bandwith” should be turned off, right?
Or do you think this is wrong?
Thank you, @Verona
