Stockfish not working on game analysis.

It's been a while since stockfish stopped working on games.
(Using Chrome on mobile).

It still works after solving/missing puzzles, though.

But on games or even the plain analysis option on the menu, it doesn't. You turn it on and it only evaluates from cloud. Once you reach a certain number of moves it simply gets stuck loading forever.

If you turn it on in the middle of the game, loads forever. After requesting a full analysis, the blunders and errors appear, but nothing that deviates from the moves of that game gets analysed: still loading forever
Used to work perfect. When I hit the analysis button on the site (chrome), it throws me to the app. Started doing that about 2 weeks ago
Still working.... This is so sad.
It's not some limitation because it Does work in puzzles, it's just a bug.
Have you been hitting the blue "+" button next to where it shows the depth? I find that on my tablet analysis works, but too slowly to bother with. On my desktop everything works fine.
King dave, I don't see such a button....

I see on the left an ellipsis icon moving (a loading icon)
In the middle, two plain text lines: "Stockfish 14+ NNUE" and "Loading...".
On the right there are two buttons: one like a target that changes the text to something I translate as "show threat" when activated, and the other is the on/off button.

When it's working (it always works after puzzles), the icon becomes the position evaluation and the line that says "loading" start showing depth and nodes.
@DanMoller What do you see in that area after you run "Request a Computer Analysis"? After turning the slider to On, I see:
+0.3 Stockfish 14+ NNUE
Depth 53 CLOUD <blue "+" icon>

The meaning of the blue icon is to extend the analysis deeper. Unfortunately, my guess is that it will hang for you the same way it does when you try to run the engine directly.

I'm not exactly sure how it works, but it appears that when you run the engine yourself, it is being run in your browser. I say this because when I turn on analysis I see the CPU and Memory usage of my browser both jump up. Maybe someone can explain how this is supposed to work.
@kingdave2 , the point is simpler than that.

Independently from how it works, it DOES work exactly as intended if I fail a puzzle and turn stockfish on (on a puzzle streak for instance). The analysis is performed in real time as I move, and the more I wait, the deeper the analysis goes. Stockfish suggestion arrows keep changing to reflect the new results as it goes deeper. (This is the intended behavior and also how it used to be everywhere, puzzle or game. My device does its job fine)

However, it simply does not work AT ALL if I turn it on for any game (independently from having or not a server analysis performed). If there is a server analysis, static server evaluations from "cloud" appear. If I deviate from a precalculated position, real time analysis "should" take place but it doesn't.

It's not about settings, depth or my computation speed. It is a bug. It works perfectly on one section of the site, and doesn't work at all on another.
I've noticed an issue in the mobile emulator, I don't know if it applies to you, but it freezes the calculation, just seems to go on forever. The console shows something like 'Cannot allocate 1024MB of memory'. Have you a large hash size configured? Maybe you can try that or at least take a look at the developer tools console and see if you get any indication on why it fails.
