Since past two days I have been trying to retrieve my existing booking and whenever I do that using Manage booking or from My trips section of the website, I see a loading icon forever. Behind that I could see my booking reference number and flight details which can't be acccessed because of this never ending loading icon. Has anyone faced this issue? Their website is already very slow in loading for the past many months,

It's impossible if I have to make any seat changes or do other things. The only option I'm left with is to call them and wait 30-40 minutes before someone even picks up my call.

Steps I've tried:

Tried all browsers : Safari, Firefox, Chrome, MS Edge. Cleared history as well.
