You might remember this...
"Version 7.35 (4mo ago): Fixed a bug which caused Factorize to incorrectly treat numbers with a single factor and an exponent higher than 1 as prime numbers. Thanks @kopárgyopár!"
It turns out that the bug was fixed within the app itself, but if you attempted to share such numbers, a similar bug would occur.
That has been spotted, fixed, sealed, and done.
