Update (October 26):
Google officially called Google Photos’ pictures missing from Web issue fixed. Here’s what Google employee Ben (who is also the Community Manager at the official Photos forum) said while confirming the fix:
Original story below:
Last week, several Google Photos users started complaining that the service’s Web version was not showing recently uploaded pictures, despite being successfully backed-up on cloud.

As can be seen in the following user shared screenshots, a picture dated October 20, only showed up when searched with the keyword:

And if there were still any doubts about that, those were quelled after mainstream tech media highlighted the problem.

We can also confirm at our end that the issue has indeed been fixed, as now the recent uploads do show up on both desktop and mobile websites.
