I have been a long time owner/user of Sam Broadcaster Pro and now Sam Broadcaster Cloud, but recently (July) started to try live streaming (first from my computer with Sam DJ, but recently with apps). I had trouble at first with the PC, but a tech rep named Mathew found that my account was not on their live streaming server. He changed it on July 30, and everything worked. Once the PC was able to interrupt the station properly, I downloaded 3apps and configured them for use (July 31). They worked perfectly, all three (iziCast, PocketStreamer, and iCast 2). Again, that was July 31st... I tested them again in late September because my station had a few events that we were scheduled to attend, and wanted to live-stream via the apps. However, now none of the three apps worked. I had previously download the Sam Broadcaster Cloud app so that I could remotely MANAGE the station, in which I found it to work well at. I did not know that it had live-streaming ability since it is not covered in their tutorials. Mathew told me how to do it, but when I tried I kept getting two errors, “live streaming failed” and “failed to connect to mobile live streaming server”. When it gave me the “live streaming failed” error, it connected for 1second and disconnects. I noticed that the app would connect to the station 3 out of 5 attempts successfully when my phone is set to WiFi, but 0% of the time when my phone was set to cellular. This happens on my iPhone 8+, my daughter’s 8+, my wife’s 7, and my 6+. I told Mathew of this and he said it must be my carrier (AT&T). I spoke with AT&T for over 90 minutes and they see no problem with phone or service. I spoke with Apple at the Apple store for almost 45 minutes. They checked my 8+ and 6+, finding no problem with network or settings. To be even more certain, I paid the additional $5 to activate more mobile DJ licenses and set my business partner in NJ up with the Sam app and credentials. His worked on WiFi but not cellular just like with me (and seemingly another reviewer of this app from 2018 who had the same problem). HE USES SPRINT!!! How could it be two wireless carriers at fault (AT&T and Sprint)? Not to mention the other 3 apps failing to connect. Support keeps telling me that it has to be my phone. 5 phones in total? 2 carriers? With 0% success over cellular? I do not carry a computer/modem combination to live concerts to live-stream events, so WiFi-only capability won’t work for us. It has been more than 2 weeks back and forth with Sam support, and now they stand firm that it is somehow not their problem. ZERO STARS FOR MOBILE STREAMING!!! (The App Store wont let me leave it at zero, so I am leaving it 1 star. Really disappointed...
