I believe you because you're not the first one mention this issue. However 6 pro from time it was the newest Pixel until now, never had a waiting time more then just a cpl minutes. Technoob here so a queation about why you mention about the amount of apps, the updates are GrapheneOS and not something to do with the apps you did instal manualy? If I'm wrong, then one (or more apps) might be the problem because I'm not experiance the same. Around 55 apps here.
