Please stand by while smartsheet is loading

Hi all

In our school it seems some users are having issues with logging in to smartsheets

In my Pc i can log in no issue along with another machine - This rules out network/firewall

On another machine i have logged in as test teacher and then log in to myself to smartsheets and it fails

If i log in as myself to PC and smartsheet it works fine!

I have another user who is cloned to me but doesnt work for them too!

Edge works so its just chrome

Any ideas on what else i can do to check? TSL 1.0 and 1.2 is ticked too
