Hi rhiamom!
Sorry I didn't respond to this sooner.
I do work on a MAC and can reply via firefox and safari.
If you haven't alerted the IT team to this issue yet- please do (they will respond... though probably not until next week because of the holiday).
I would send this to them- but I don't have my work computer.

Sorry about this. Let me know if you don't hear from them in the next week.
I am thankful you joined our community and I want you to have a better experience!
Have a great holiday weekend!
Sincerely, Cate
