Account link& Watching the race in the browser version

For App that's a good question. The only way coming to mind would be selecting the (own) team from league, or driver/staff employment if in no league, hit the share button and select a browser or notes app and copy from there. But there might be better ways, I'm not that well versed with the App as I usually use browser except for, recently, live races and testing/checking stuff.

I have no iPhone and use oldschool email/password so accessing/migrating accounts just happens for me as long as iGP Manager runs and I have any potato able to run a browser available. :-)

So you could also set email and password in your account options. The only slight discomfort in giving that advice is that very few people had an account problem doing just that and needed support to fix account access again. There are also other authentication options to bind the account to but in my view that adds just another layer of relying on a required external service to be accessible and working.

It is possible to do live racing but the browser version only supports 2D.
