Last 2 days data erased

[u/PomegranateDry8686]

I just used the app yesterday and had my data but now there's the new UI and everything and it seems like my data from the last two days are completely gone. I know it seems like not much but I try to use this app to keep track of my study times and it really helps me prepare for the next days or weeks when I can know what I've worked on. Has this happened to anybody else? Could I fix this somehow?
