Also a wide bug is not to include the ipv6 stuff in SPF, did you checked this, in the past creating a extra transport for google only via ipv4 was helpfull too
amazon have around 800000 ipv4 adresses in there spf, is this nearly as good as +all :(
why spf is not have a max ip in there rfc :( gmail is 2nd place there https://dmarcian.com/spf-survey/?domain=gmail.com its more important that spf is maked right then fight ipv6 ipv4 problems
