Hi Laxuzv,
Thanks for visiting Microsoft Community.
It appears that you've encountered an issue in Loop where the "Update Cover" button remains in English regardless of the language setting. This seems to be a specific quirk within the example workspace provided by Loop, as it does not occur when you create a new workspace.
Firstly, ensure that the language settings for your Microsoft account associated with Loop are set to Spanish. To do this, log into account.microsoft.com and navigate to the Your Info section on the left-hand menu to verify if your language is indeed set to Spanish.
Next, relaunch Loop. From the main interface, accessed by clicking the Loop icon in the top left corner, proceed to click the plus sign in the upper right corner of the screen to create a new workspace. Within this new workspace, select "Add cover" and choose any cover image to confirm. At this point, you should notice that the "Update Cover" button is correctly displayed in Spanish.
If the translation still does not appear as expected, try signing out from your Microsoft account in the upper right corner of the interface and then logging back in.
We hope this information helps resolve your query.
Best Regards,
