Need to manually enter attendee email addresses

I need to schedule 25 to 30 zoom meetings a week and until recent I would set up the meeting day and time. I would then be able to enter the attendees by starting to post their email address. I did not have to enter the entire email. Now, the system does not do that. Instead, I have to manually type in the entire email address. Not only is it more effort but it increases the chance of error. Any advice? Thanks in advance.
