I downloaded one of the apps and for some reason it won’t let me check the tasks, it only goes as far as the download option. I used the link provided for download, used the help centre and tried clearing my cache, waiting awhile, deleting and redownloading but it still won’t work. This is the first time the app has done this so I’m not sure if it’s a glitch or if there’s something else wrong
