Please help Zoom Visits

[DRit]

My company is having us do zoom visits with patients.  We are required to copy and paste the personal meeting linking into our company email and send to the patient (instead of an invite).  Whenever I send the copied link, the person on the other end is unable to open the link (error:  invalid meeting id).  The id does match the one on the invite (that works)?  I did check the box (use this id for instant meetings).  Any suggestions to get the link to work?  Thank you.
