OK. I've just done battle with my Android phone, Google Play and the Abbott websites and succeeded in installing version 2.10 despite the confusion. First I went to the Abbott website on my PC which says 2.10 is available (well sort of). I clicked the Google Play icon and went to download 2.10 onto my phone. I had to do various things to get the Google website to know about my phone (look at devices on the webpage). With this knowledge I clicked on install and my phone magically updated Librelink.The frustrating thing is that on my Desktop PC when I Google Play Store version 2.10 is offered.
