The iPhone ios14 version does not log on to the embedded web page?

Hi neilson6913,

It seems like you faced some issues accessing the power bi embedded content with new version ios systems. Did this issue only appear when you use the higher version ios system web browser? 
If this is a case, I'd like to suggest you use fiddler to trace the steps and requests of the detailed operations and share some detailed information here to help us clarify your scenario: (notice: please remove the sensitive data before share)

Capture Traffic from iOS Device 

BTW, if you use other types of web browsers, did this issue appears again?

Regards,

Xiaoxin Sheng

Hi XiaoXin

Other versions of the browser are all right, only ios14 can not log in,

I have provided you with information through Fiddler, and then please help solve it, thank you!
