OK... Let's see...
We still can't post our own videos to instagram. We still can't get a full functioning fb app. IE on WP can't even load Bing search results right a lot of times. We can't even add people to speed dial from the people app. It's one thing to implement big changes but these things seem so small to do. Does Microsoft just not care at all? How many times do we have to ask for small features before we get an answer? This is getting ridiculous.
Did Microsoft acquire Instagram? How are they responsible? Replay that first sentance and insert FB... I really don't understand how so many users want the OS to be held primarily accountable for 3rd party services.
Instagram is ignoring you.
Facebook is (infamously) ignoring you.
"Dear Walmart,
Burger King won't sell me the type of french fries I want. Fix it."
Makes just as much sense.
Speed Dial? It's right there. Open your Phone app, scroll over to the Speed Dial page and tap the + symbol. It opens your People app and you simply tap on the entry you want added to Speed Dial. How is that significantly different from what you are asking? It's the same number of steps as open People App, scroll to the entry you want to add, open the entry and tap on some add to Speed Dial option. How is this an issue? Simply the order needed to accomplish it? If it was done that way on one OS does not mean that all others have to follow that format.
I'm not experiencing any issues re: IE loading search results... Do you have any examples?
