The MetroFax has worked reliably for me for half a dozen years. (This and other branded fax services seem to all be run by the same parent company behind the scenes, FYI.)
However, MetroFaxSendandReceiveFax doesn’t do what the web site does.
Using MetroFaxSendandReceiveFax on iPhone X, iPhone 8, iPhone 6 and iPad Pro 12.9 all report the same: Sent fax view doesn’t update.
Neither do any of the other views. Push notifications don’t work to alert you to a success or failure either.
There are no updates to the Sent Fax view, even though faxes fail or are successfully delivered, despite several attempts to refresh views.
Email alerts work when you use the service from a full desktop web browser, email alerts do not work when you attempt to send a fax from the mobile app.
I’m going to cancel this service. We pay 120 bucks a year over and over and if I can’t use MetroFaxSendandReceiveFax, then I will look elsewhere. ScanBot Pro has a fax service that works, so I’ll likely transfer my $$$ to use that instead.
