Do not see the eOS update anymore

You could always do a manual update, but while on this idea … would you like to try this, as it is a fix I seem to have to use for troublesome apps.

Settings > Apps and notifications > See all … apps > 3 dot menu, top right > Show system > Updater > Storage > Clear storage | Clear cache

Then restart the phone.

Be aware Clear cache is the gentle option. In the case you want to clear a defect, then Clear storage/data is likely to be required. This will delete settings within the app, so you are likely to need to re-enable “Check daily”.
