It's compatible with Google Android smartphones and tablets v2.3 or higher so not sure why this would happen.
Did you try the emailing option for the link instead of via text? Also check for competing software that may already be installed
I have it on my Android tablet and it works fine.
I would call Technical Support back and ask for escalation.
I forgot to say, make sure you've selected the right sort of device on your account page too.
I did have the correct device type.
There is no antivirus of any kind on our phones yet so I don't think there would be a conflict.
I successfully installed on the tablet but not on either of our phones which is puzzling because all 3 devices are running the same Android software version: 5.0.1
Technical support was also puzzled and were unable to provide an answer so I had to cancel the purchase; unfortunate because it looked like a great app.
Thanks for your help.
What a shame, sorry things didn't pan out the way they should.
My phone, which I rarely use, is so ancient it's not in that league and all my friends have iPhones so not much help there either.
All the best ;-)
