So I just bought a Lumia 920 and I like. I like a LOT. However I have one single gripe which is keeping me from using it over my Galaxy S3. The official Twitter app. I don't know what I"m doing wrong but it won't let me tweet URLs. I enter text into a tweet, paste a URL into the Tweet and while I'm NOT over the character limit for a Tweet, the client won't let me post it. As soon as any URL is pasted into a Tweet in the WP8 twitter client the "send tweet" button greys out and I can't do it. Any thoughts? No I don't want to use Rowi - I'm perfectly happy with the official client aside from this one single issue.
