myaccount Ros

Is it just me or is anybody else having problem using my account today 1.9.23 on Revenue ROS ?
It lets me enter all details and just when I get to signing and submitting my form I get a red circle wiyh a line through it blocking me from entering my PPS number .
Nobody answering the helpdesk , voicemail says the queues are too long. Tried switching browser from Microsoft Edge to Chrome but no difference.
Error ID: myAccount-5004031540784999137

I was able to log in fine just now using Chrome on Android.
In case it matters I log in using my PPSN, date of birth and password.
Not using my MyGovId because they could never get that working for me on myAccount even though it works ok elsewhere.

I've been logging in throughout the morning, off and on. No issues.

Must be me so
