I understand your perspective regarding the recent changes to the invoice layout, mikemike236. It is natural to feel apprehensive or even resistant to modifications, especially when they involve familiar systems or interfaces you have grown accustomed to using efficiently over time. Your desire for the ability to revert to the old one is a valid and relatable sentiment that I fully recognize and appreciate. 

Before the end of May, new and existing users will be migrated to the new experience with no opt-out, except customers who use Time. They will be held out of the migration until the feature "Group by Time" is built, which is scheduled to be ready at the beginning of June. We are diligently working to improve our products and services to meet your needs.
