I sponsor 4 girls. When I looked at the letters in the app, a letter and coloring page for Tanyalak (TH082209052) was accidentally scanned into the account for Sarita (TH028500593). I just want to make sure the right person gets the right letter. I do typically send my letter and coloring pages for 2 girls in 1 envelope to save on postage. Is this a problem?
