Errors should fixed* - apologies.

We suffered development delays due to incorrectly estimating the time required to implement certain features [1]. With fixed resources and the need to meet our street date because of the significant marketing spend [2], some unfortunate errors slipped through.

A release-day patched has been rushed out so our product meets the standards our customers [3] expect.

*Errors may not actually be fixed.
[1] I was late with text…sorry.
[2] Well…our marketing spend was zero but, if I remember, I might tweet.
[3] You paid money!?
