I've been having the same problem. I've been using the support feature in the app haven't been any help yet. I'm the admin of my org and none of the settings have changed for my login. Previously when used this app and added an account it would ask me if I wanted to stay logged in. I've deleted everything, cleared cache and app data, uninstalled everything, and I've never seen that option again when I add my account again. When ever I login I see a bunch of screens pop-up and they disappear and I have no idea what it's doing.
Using Outlook for Android for personal email and calendar management

Yes, I registered my phone in the Microsoft Authenticator app for android and that has seemed to fix it.
One thing I'm not sure about that stands out to me reading your previous posts is your current config with accounts spread over three tenants, personal/business/business. I have tested the other issues, related to multiple applications for a single account within different tenants, up and down for the past week, but nothing with cross-tenancy or personal accounts. Unfortunately most of my information is conjecture based on testing different configurations and an understanding of the protocol, so I don't truly know what's happening on the backend to understand all the possible conditions.
We may also be conflating separate but similar issues. But the Aquamail appears as a completely separate application in Azure and would not interact with tokens from Authenticator at any rate.
We are experiencing the exact same issue for the past week, and have opened up tickets with 365 support, Outlook mobile support, Teams Mobile support, and One drive mobile support. each team is telling us to open the ticket with someone else, and nobody can suggest anything more then disable MFA, or remove and re-install the app.
I'm not 100% sure that is my issue, the more I think about it.
1 - I haven't used Excel / PowerPoint since April (maybe something is open in background?)
2 - Android is able to get new messages since it actually shows them on the notification screen, but they don't show up in Outlook app
I wonder if the background notification mail check/preview code works differently than regular outlook?
On the other hand, I installed AquaMail and it hasn't complained once. Since that is a non-MS product, I'm guessing it wouldn't be sharing with the other MS stuff which could support your thought.
Not sure.
Teams and Outlook seem to be the worst, but I have triggered this with OneNote. Azure AD shows the pattern for "Microsoft Office" applications in addition to Outlook and Teams.
So what I imagine is when you open Excel/Powerpoint, "Office" on your mobile will generate an access token with your credentials that is good for an hour, and a refresh token. Refresh tokens are good, typically, for 90 days, and their lifetime extends every time a new access token is generated. Your app will send the refresh token to Azure when the hour is up to get a new access token.
My theory is something about the "shared" refresh token isn't liked across applications. So, the next time Outlook hits its hour window, and an Office application has last modified the refresh token, it asks for sign in again.
At that point, if you never sign back into Excel or Powerpoint, nothing else modifies the refresh token and you can continue on without ever getting another sign in request. The office suite and Teams don't request for sign in with a notification like Outlook does, so the problem isn't noticeable from that perspective. But if you're to turn around, open one of the office apps and either manually sign in or encounter that flashing "pick account" dialog which is generating a sign on event in Azure AD, your Outlook will request login within an hour or two.
I think Authenticator is successfully brokering the connection for all the apps but the applications aren't updated yet to understand the data being returned by the app. They get an unexpected response and therefore believe they need to sign in again.
Again, if you're not using Authenticator, all the applications generate their own access and refresh tokens that never interact so the token thrashing never becomes an issue.
