Users unable to get email notifications on followed sites, or documents: System.IO.FileNotFoundException and Microsoft.SharePoint.SPSite.InitUserToken(SPRequest request) errors

Question

Hi Community
I have an issue on a live SP2013 farm that is really causing me grief.  Although  I ( Farm Admin)  and my other users can follow items which are subsequently  confirmed in our respective News Feeds - 
none of my users are are actually getting emails notifications . 
Alerts ( did) work fine.
I have written some PS to vew and set  the SPS-EmailOptin for each user
$up[$upManagerAttribute].Value = $managerNTName
# check if the email check boxes are unchecked '1' then if so check all
write-host -fore white "User Profile for user"$NTName "Now has email opt in currently set to" $up[$upEmailOptin].Value
if ($up[$upEmailOptin].Value -gt 0)
$up[$upEmailOptin].Value = 0
write-host -fore white "User Profile for user"$NTName "Now has email opt in all checked."
Very few are unchecked. $up["SPS-PrivacyActivity"].Value = 4095  is set for all users as in
the the privacy settings on the newsfeed are all checked
For my currrent client I  set up a development intranet which had the seperate web apps for the main portal and mysites. Test users were able to follow documents, sites without any problems.  Before go live I was asked to accomodate a requirement
where there is only one web application (don't ask!)  effectivley http://myintranet 
so mysites sits under http://myintranet/mysites .   I  made the appropriate changes to my AutoSPInstaller scritpt and al appearedd l good : services , Service appplications, mysites are all started.  I am using
the two app pool accounts  one for the portal and one for mysites.
A quick look at the the releated threads on this forum indicated permssions could be DB permissions  related tho I  am not seeing anything in ULS to strongly point to this
$webApp = Get-SPWebApplication http://myintranet
$webApp.GrantAccessToProcessIdentity("mydomain\SP_ProfilesAppPool")
- checked and SPAcess Data is given to the mysites app pool accout to the portal web app .
I am seeing some odd errors in ULS
Ignoring the space ' critical' warning which I have flagged up to Ops and  I doubt is my real problem.  The errors I see that are related are :
System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0x80070002), StackTrace:
