I have changed privacy settings from ‘Just Me’ to "Everyone’ and only activities since that moment are public. I would like to have an option which makes all activities public from now but also from the past as well. I have changed it weeks ago therefore I don’t think that waiting for making it public makes sense anymore.
It could be also the fourth option ‘Everyone’ but only from now.
It definitely should be changing all your activities when you change that setting. I’ll take a look…
Update: I’ve fixed the data, so your activities should be public now. I also fixed the underlying issue in the form which caused activities to be interpreted as private. After I release that, I’ll take another look at the data to ensure everything is set appropriately.
