Wrong ID (former) appears in Apple Store when trying to update apps

I wanted to manually update my Messenger app in the App Store, and it asks me for a password while showing me my former yahoo account mail ID (account to which I do not have access to anymore). In 2017 (approximately) I changed my email account associated with my Apple ID, I dropped that old yahoo mail and changed it for my gmail, a long time ago (we're in 2024 now).

I tried updating other apps, to see what would happen, and most actually worked without even asking me my ID. Only Messenger and an old Convertit app do this when I click to update them.

My ID is perfectly set up in all my devices, 3 apple computers and two Iphones, meaning that when I go into system settings my Apple ID is correct, it's my gmail account that appears, same thing when I doubled-checked on iCloud.com, the correct ID (gmail) appears there. So I'm thinking this might be some sort of IOS bug that's bringing back a very old former ID, but I have no idea how to fix this. I read a suggestion on a forum, to de-install completely Messenger and reinstall it, but I want to make sure I won't lose any messages that way. And actually, I would love not to have to do even that, if there are any other solutions. My iPhone is an SE, the IOS version has been updated on it weeks ago, version 15.8.

If anyone could help, it would be very much appreciated !
