I've seen this phenomenon and reported it before, but it was always around 4am in the morning (Central Time), but today it has persisted even up to now 7:54am.
I've added several transactions and each one has defaulted to yesterday's date, 6/22/26. When I hit the calendar to update to the 23rd, it shows that today is the 23rd.
Not a biggie, but weird.
Here is a screenshot I did just now at 7:57am:
This was in the Visa account, but has been the same for my Checking account and a manual account as well.
Edit: I closed the browser and reopened it, and that fixed it. I think I kept the window open all night. I remember now because when I got up, I was perplexed as to why Simplifi had already updated my accounts. So, as usual, the simple thing is the thing to try first. With Safari, closing the window doesn't necessarily close the app.
