Windows 10: Email Not Displaying Properly

For a while now, some of my received emails have not been displaying properly using the stock email app for BOTH Windows 10 & 11. Instead of text & pictures, I'm receiving formatting code?.This doesn't affect all messages, but it seems to be consistent in terms of the sender.I've seen a topic or two posted that discuss similar issues, but they mention specific email services such as Yahoo!.Is there a known bug out there that is causing this to happen?I could try moving the email accounts to Outlook to see if that resolves the issue, but I'd first want to find out where things stand w

LinkedIn emails not displaying properly

In my oem email app emails from LinkedIn display as if the right-most quarter have been chopped off. This only happens with LinkedIn emails. I contacted LinkedIn and after an investigation they concluded the problem is with the app and suggested I use the
app MetroMail. Their emails display fine in MetroMail but other than the display issue with LinkedIn emails I prefer the oem email app.

LinkedIn emails used to display fine but several months ago they started displaying as per above.

I don't see anyone else posting this issue so maybe there is something specific on my app? Any thoughts?

Corrupt cortana not displaying properly

As per my below image, when I open cortana the display does not look right. There are three options under "can I be of assistance?" (or one of the other sayings things it puts there) which only become visible when I hover over them. I don't believe this is the proper behavior. Also in the "pick up where I left off" section it just oddly shows icons of the program I was using and doesn't give the name of the file. I don't believe this is the correct behavior either. Clicking on one of the icons opens up a recent file.

I tried following these steps with no luck - Reinstall and Re-register Cortana in Windows 10 | Windows 10 Tutorials

Any other suggestions are welcome.

LinkedIn emails not displaying properly

Please stop using a hard reset as the first solution. Its not the OS its the app. Their emails display properly in the MetroMail app. Please have someone update the OEM email app and publish in the Microsoft store.
