Hi @esumft
Thanks for posting! I tried reproducing this today and found that I could not reproduce the issue - when inviting a GMAIL address from both my personal and team hubs, it went through regardless of capitalization.
Are you receiving any screenshots or error messaging when the capitalization issue occurs? This could be a unique issue on your end - please record a screencast if you can create a project, invite an email address with some capitalization errors (and have the email not show), then create another project and invite the email with the correct capitalization showing the invitation email. Seeing the problem in a video may help me find anywhere where my workflow differed from yours.
Please let me know if you have any questions - I'm happy to assist.
