New member here. Just tried to set up call blocking and noticed the same thing. Also noticed that when I tried to select the days of the week to block the calls, the individual day blocks would alternate between selected and deselected. Took a few minutes for all of them to stay selected. Also when I try to select sms block it affects the days to block selections as well. For instance Saturday will deselect when I attempt to choose sms blocking.

Have not tested the functionality of the feature yet as I am waiting to see if the number shows up this afternoon…

Other than that issue I must say I am happy with the product 8). Hope you guys figure this out.
