Since the release of Shift 2.9.0 on May 4, 2018, several performances were reported by Shift users. 

These issues affected the responsiveness of Shift with a portion of users reporting lagging issues when composing and scrolling through emails. 

Shift developers were able to deploy a partial fix with the release of 2.9.3 that solved roughly 80% of all performance issues. However, a small portion (20% estimated) of users remained affected.

With the help and cooperation of multiple Shift users, we were able to identify, reliably recreate and develop a release to solve the issue affecting the remaining 20% of users. 

We'd like to take a minute to thank all our users for their feedback, cooperation, and patience as our team worked through this issue. Thank you

-The Shift Team
