So, anybody who updated to android 10 knows about the annoying suggestions appearing in settings, which at the moment can't be dismissed or swiped away. Clearing the data of Settings Suggestions app can "fix" the issue momentarily but it'll come back again. Seems like the issue is about suggestions.xml file (/data/data/com.android.settings.intelligence/shared_prefs/suggestions.xml) not updating the boolean values correctly.
<boolean name="com.android.settings/com.android.settings.wallpaper.StyleSuggestionActivity_is_dismissed" value="false" />
<boolean name="com.android.settings/com.android.settings.wallpaper.WallpaperSuggestionActivity_is_dismissed" value="false" />
I'm attaching the zip containing the edited backup file that you guys can restore using "adb restore data.ab" command.
NOTE: The restore process won't work on old adb drivers so make sure you use the latest platform tools before trying.
