Hi Refyne!
In scenarios such as this, more in-depth troubleshooting on your context would typically be required, to understand the failure stage and root cause of failing to log in via a certain OS or device type.
As this may involve detailing private information pertaining to your dashboard or configuration, I would recommend to open a support case if you are still experiencing this issue, via any of the channels as noted here:

Let me know if you have any further questions on this too!
