App is incompatible with Kobo - why?

Hi,

I'm hoping someone here will be able to help / have some ideas for me. Not sure if this is the right place - I also tried the Tablet forum - so apologies if it's not.

I've just released an app on the Google Play Store but I've been contacted by a Kobo user to say that when they try to download it, it says that the app is incompatible with their device. I'm trying to work out why. They say the have a Kobo 7.

I'm guessing it's to do with the permissions that are required to use it but I can't find any evidence of this. I've seen that the GPS requirement causes problems but my app doesn't use that so it shouldn't be the issue.

Here are the list of requirements. Do any look suspicious?

• Open network sockets
• Write to external storage
• com.android.vending.CHECK_LICENSE
• Access information about Wi-Fi networks
• Access information about networks
• Record audio
• keep the processor from sleeping or the screen from dimming

I've tried contacting Kobo a couple of times but they're dragging their feet. I think this community is probably better!

Thanks in advance!
