That's like… every fucking browser in the world including the one you made, MS... wtf?

Microsoft Partner Center (aka Windows Dev Center) is a fucking joke.

Btw this is a slightly more serious "error" than the one you're reporting… inception of exceptions.

Try Firefox and never look back

Man I kid you not some stuff I have to submit (for some grant) online into this weird system. There is 2 of it with the same name. Same base URL. One is version 8 something other is version 1 something. Yes you need to register to the older one. OK so while filling the form it only works in Firefox. Not internet explorer. Not Chrome. No edge. If you don't ise Firefox the date fields will not validate even though it's validated server side. Then if you don't fill all the fields you lose your whole progress and have to restart from scratch. Also since it sometimes updates the form while you're filling it (like when entering postcode it fills out the city name) it reloads the page with the fields set but if you don't have all other mandatory fields set it will throw you out give a Runtime Exception and die on you,and you loose all your progress. Took a few hours to even register because it kept resetting.
