Hi all. I haven't used a Libre CGM for a while, but I'm trying to make changes to my diet so thought I'd get a couple for monitoring. I put one on my arm on Friday, but I cannot get the app to work. I get to the scan screen, but the 'scan' button doesn't appear to be a button at all - it's just text. Not even an error. I've uninstalled it, cleared the cache and data, rebooted my phone .. in various different orders. .. but still nothing. Has anyone else had this? Thanks in advance!
