An option would be to go to the recently updated ones and skim until you see the date from 10 days ago and you can see the covers of every single updated manga, it's a hassle but you could wind up finding new interesting mangas from the cover.
I also had a similar situation months ago and did it like that skimming through all the past updates.

In Mangago's notifications section usually u can see the last 50 days of updates, I can't always check on the site and read the daily updates so it happens sometimes that I don't log in in months. Today I came after a looong time that I didn't check my notifications and I wanted to read every one of them BUT IN MY NOTIFICATIONS I CAN ONLY SEE THE LAST 10 DAYS. Can someone explain why? Is there another way to check if the comics I'm following uploaded a new chapter in the last few months? Pls help me
