I have completed week 1 (and actually did an extra day 1 as I downloaded the wrong app first time!!) . It is much harder than I thought and is not getting any easier!!
Also, I have downloaded the app onto my work Samsung A£ 2016 phone - the app tends to throw me out before I have finished!! I am getting a lot of ad pop ups so think this is what is interrupting the app!? I have tried everything to stop the pop ups, including downloading software recommended by google! anyone else had the same problem?
