I registered to Upwork in 2018 and I never used it. I ended up in Upwork website again now becaue I googled my name and I found out my profile is public. I entered my account trying to modify it but when I apply the changes the website says I should enter my phone number in order to get an auth code and approve the changes. When I enter the phone number, even if it is 100% correct (I tried with the international prefix, without it, with the starting 0 and without it), it gets stuck. I checked from Chrome dev tools the response and it says it's a 400 error with an invalid phone number entered. Is there anyone who can help me?
