Your device isn't compatible with this version

I have Norton Security Deluxe 2021 5 licences but it won't install on my older phone.  'it' goes to Google Play store the following message is returned "Your device isn't compatible with this version".  It dos install on my Android V10 phone.

As far as I know Norton Security 2021 should install on phones with Android V6 installed.

My phone details are:

Make/model - Wiko/Robby

Android version - 6.0

Android security patch level - 5 November 2017

Kernal version - 3.18.19+

Build number - MRA58K release keys

Custom build version - Robby Marshmallow 6.0 (41)

Please can anyone help, I use the phone as a WiFi hotspot and so security is important.

Thanks in advance.

Unfortunately, the product announcements often lag behind the changes made. About a week ago I noticed in Google Play that the minimum OS version had changed to Android 8. I was about to post that to your thread when I got notification of the Product Announcement. 

 

Well that's a bugger!!  I suppose it was annouced today but the actual end of support ocurred a few days earlier as I've had this problem since September.

Thanks for your efforts.

 

Just as I was about to confirm on Google Play Store, Norton has announced the end of support for Android 6 and 7. See this announcement...
