I use Evernote to keep notes on my daily tasks and meetings. I checked my daily tasks on Tuesday night and prepared the next day's plan, everything was fine. After some time, I wanted to check something from my note and there were some missing parts. For example, the next day's plan, the current day's completed tasks, and notes from a meeting held for 3 hours. Is there a way to solve my problem? Please help me these are crucial notes that I need access to.
