M1 Touch stopped working - license error

[Linwood]

I rarely use this as I have not been travelling, but leaving for a few days and fired up M1 Touch for the M1G and... 
 
License error.
 
Same Android, same install, nothing changed since the last time it worked.  Google account has not changed.  Just logged into Google and it shows "installed" for my device, no errors.  (Their FAQ online says disabling the google account is why this occurs, but I have never had but one google account, and it is active and working).  And everything else I've tried on the Android is working fine.
 
I've written to the indicated support group, but will have to leave without it working.
 
This was a VERY expensive application, if I recall.  To yank my license without notice is completely unacceptable.
 
Anyone else having issues?

Hi,
 
​Google Play will license the M1 Touch app based on your Google Play account that you download the app with.
 
If you remove the Google Play account you downloaded the app with from your device, then the app licence will also be removed.
 
This is how the Google Play Services works. 
 
For you to say nothing has changed, then something has to of changed for it not to work, and now need to work out what has changed or find out what is not working in the background.
 
If you open the Google Play page, and uninstall the app and then try and download the app again, does it ask you to purchase the app again or does it let you install the app without purchasing it again?
 
If it asks you to purchase the app again, then Google Play Services has an issue with your device or the Google account you purchased the app with is not on your device. If this asks you to purchase the app again after uninstalling the app, then contact our support so we can fix it up for you.
 
If it lets you install the app again without having the purchase the app again but still comes up with a license error then contact our support.

Thanks.
 
Support responded very rapidly to my note.  I had left home, so was unable to follow up until now.
 
I had purposely disabled wifi before trying to connect to force it to an outside, not internal LAN, connection.  My cellular coverage is weak, and my guess is that it simply failed to connect on the first try.  This thew it into the "not licensed" message, which is misleading in that case.
 
Apparently the app, once, checks and if it cannot reach google rather than saying "no network" says "no license".  On the good side, I understand that once it does connect it stores a token so that subsequent failures to connect will get a more appropriate answer.
 
Contributing to my issue was that I do not think I have used it in over a year.  I think in that time something else happened - maybe an OS upgrade, maybe a long ago version upgrade, which wiped out my settings.  In and of itself not an issue as I knew the settings, but it contributed to my impression that I had lost some kind of permission.
 
So back home now, no license issues.  But I still can't connect, even internally.  Working through that.  Might be my issue, struggling as there's no symptoms given but "can't connect".
