Hi, It has some sort of bug however if you know little about HTML/CSS you can do a trick to search and choose the email.
When you’re trying to choose an email from list and it doesn’t show up, follow the instructions and it should temporarily work for you.
1. Click on any field i.e Completed/Processing/On Hold
2. Type any letter and wait for 5 seconds
3. Right click on any field mentioned above and click inspect elements
4. Delete the class “hidden” and hit enter. Screenshot attached (shorturl.at/vHM47)
You should now see a list of all emails.
This method worked for me. It’s not a permanent solution however, this trick might get you going.
Thank You
