Unable to delete emails


New Email
Suddenly a couple of weeks ago was unable to delete emails swiping right to left.
Also when I clicked Other, tab did not work.
The three dots, help, did not work.
I can still receive emails .
Im using iphone 8+ all other apps , search etc work as normal.
I’ve deleted the app. But not in settings. Dont want to do this as may not get hotmail through my Mail app.
I can send receive hotmail emails etc from my Mail app on iphone.
Even if I type in hotmail.com it opens up and can see my emails but cannot do anything.
Help please.
