Cannot sign into Adobe Sign app

Evening

I am trying to log into the Acrobat Sign Sign app on my iPhone but keep getting the following error:

Error 403: disallowed_useragent

Can anyone help get past this?

Hi Zoe37549125qx2d,

Thank you for reaching out.

Please let us know if you can access the service using the desktop or the web application for Acrobat Sign.

If yes, please try signing in once on the web version on your mobile device.

Share the Acrobat Sign and iOS version on your iPhone.  

Thanks,

Meenakshi
