I found some similar references to a bug similar to this one but I’m not sure if it’s exactly the same problem:
I am using Sentinel Playground | Sentinel Hub to display Sentinel natural color images. Despite the image acquisition date being correct, it is actually showing the same image from 5 days ago. I can see that there was an update further east (another sweep) but not of the area of my interest.
To add an explanation, Sentinel Playground makes a mosaic of data from different dates over the displayed area, so that there is no area without the data. This can be interpreted as displaying data for a time span, where the start is the first date the selected collection was available, and the datepicker limits the end of the timespan. Playground then tries to display as latest data as possible for that timespan. The single date selector can cause confusion that you select a single date for which the data is shown.
EO Browser has 2 options. The first is displaying data for a single date (yeah, with one datepicker, adding to the confusion if you are starting to get familiar with both apps). The other is similar to what Playground does - it allows users to select both start and end of the timespan for which the data is then shown.
