Not able to send/receive text sms

Hello,

Happy New Year!

I am trying to send text sms from the desktop app and from mobile device but not able to send text sms and not receiving them as well. The + option for new texts is not visible on the desktop app, neither is the option to send a new text available in the drop-down options menu on the top-right.

I recently signed up with RingCentral on MVP plan.

Kindly advise. Two image files added for your kind reference.

Thank you
