When users try to login using a mobile device, they click on the link in the email. This link is not open in the regular browser but in the “integrated browser” in the mail app.
So, the session is not persistant in the browser. They have to copy/paste the link without clicking on it… and it’s not always easy to do.
I’m not sure it is possible to force the link to open in the browser (ie safari).
But maybe receive, with the link, a specific “PIN” number to enter directly in the browser?
