I get the impression that MLBAM don't test a thing before they throw these apps out there for everyone to beta test.
The 360 issues were bad enough, but they blamed MS for that one - but the PS4 app is their doing, and it sucks. Search was patched in despite the fact it didn't work, and still doesn't. As a search function, it's useless, as it doesn't search for anything 99% of the time. The 1% of time it does search, it doesn't show you all available results anyway.
Today I noticed that they have sections for Raw and Smackdown Backstage Pass, and the Raw Pre-show, although none for Smackdown Pre-show or This Week in WWE. I clicked on the Raw Pre-show section.
"Fatal Error: Something has gone very wrong, please restart the application"
Seriously? Come on. They couldn't even code a "There are no episodes" page with a back button, so just left the app to crash instead? The network is great value and I certainly won't be unsubscribing for a long time yet, but this is just amateur.
