In settings I hid social feed on the dashboard, but when I went to the dashboard it was still there.
Is the setting actually saving? If not, could be an ad blocker or other error (should be indicated at the top of the page) preventing your settings from saving.
Make sure you are scrolling ALL THE WAY DOWN the page to click Save Settings for your ALL your changes.
Maybe a future feature could be that these settings are saved automatically upon change, or maybe adding the save button to each section (but that might get weird and ugly)…or maybe make the save button a sticky footer on that page so that it’s prominent enough for people to know they still need to click it to save.
