Mobile not registering correctly in Account

I have a Samsung Galaxy S7 Edge running Avast Mobile Security for Android and Avast Anti-Theft which isn’t registering correctly in my account.
This results in me not being able to see any information about it.

The message I get when I click on the device in the list is:

We are sorry, but detailed information for device SM-G935F is currently not available.

Can someone please advise what I need to do.

Is GPS enabled ?

Yes it is.

Try it again later (tomorrow), if it is still not working contact avast and ask them to have a look.

I’ve had it installed and connected to the internet for at lease 3 days now. I don’t think waiting one more day will help.

Hi Mark, please try to disconnect and reconnect your device to the account.

That was one of the first things I tried.

I raised a support ticket and this is the response I received:

Thank you for contacting Avast. Unfortunately the “We are sorry, but detailed information for device SM-G935F is currently not available.” is a known bug that sometimes appears on devices running Android 6. For an unknown reason the info sometimes cannot be obtained right - what results into the error. We are investigating the problem but unfortunately for now we got no workaround nor solution for it, my apologies.

I am really sorry for such unpleasant message. If you wish, I can eventually contact you back once a solution will be available.

I take it you have not had an update? I also get this on one of my Android 6 phones. On another identical phone it’s fine.
