Here is the strange thing about Shazam:
It says that i have an update in the Store app, and it's Shazam, but it is version 4.5.0.26 and that it was last updated on August 27th, which I got it yesterday, but for the version 4.5.0.27. I press Update button and i got a Store error 81030137. App cannot be updated.
I went to the Store link from my browser and here is what it is there:
And here is a screenshot from the Shazam I have intall it on my phone at the moment of writing this post:
Strange huh?
EDIT: If you occur this error, just uninstall Shazam and install it again, it worked for me, but you will get to version 4.5.0.26, which is not a big deal, no difference.
