New console update broke Series S

Thought that was the case. A while ago, there were all sorts of issues with convoys across all platforms....the Series X/S's developed issues where the game would crash to the Xbox Dahboard which they updated to resolve it...that fix also cleared up the Convoy issues on the new consoles. Coincidentally, it was around this time when Horizon Life issues started to appear and have steadily got worse.

My personal opinion is that whatever they did in the coding to sort the new consoles broke something somewhere for everyone else

Yes, it is likely that your Xbox One will not be compatible with the new Forza Motorsport dashboard update or with game updates in general, as Microsoft is focused on the new generation of consoles, the Xbox Series X and S. The Xbox One is no longer being updated and Microsoft has already announced that it will end support for the Xbox One, but has not yet said when.

Elaboration:

Xbox One at the end of its cycle:

Microsoft is increasingly focused on the new generation of consoles (Xbox Series X and S) and, therefore, support and updates for the Xbox One are being reduced.

New dashboard update:

It is likely that the new Forza Motorsport dashboard update, or other game updates, will not be compatible with the Xbox One.

Focus on the next generation:

Microsoft has already announced that it will end support for the Xbox One, and its attention is directed to the Xbox Series X and S, the most recent generation.

System updates:

Your Xbox One may no longer be receiving system updates, or the updates you do receive are only to ensure the security of your console.

Same issue here, tried it across multiple Xbox consoles too (one Series X, one Series S). Going to lose my 18-week streak if it doesn't start working today. That'll be really disappointing.

It's either tied to a connection issue with their server (not the Xbox network connection on our end) or the app had an update in the background that broke it. Either way, it's an MS problem to fix.

I have new Xbox Series S console, it have old egde browser with EdgeHTML engine. How I should update it to chromium version?

I want the new Microsoft Edge on Xbox one s

It looks like you've purchased the Series S|X edition, which is for new generation consoles (Series S and Series X) and wouldn't be compatible with your Xbox One S.
