I would just like to ask for help, I deleted certain pages of the file that I have using a third party provider software, but retained the file as PDF format. I have sent the 1-pager final file to my colleague but when he opened the file on his mobile phone, the file he is seeing is still the original 21-pager file with the file name of the individual file.
When we tried to open the same email on laptop, it is still a 1-page file.
How do I solve the issue?
Share or review PDFs
At first glance either that third party tool did something wrong or there is an issue in your colleague's phone (e.g. his phone might display the whole pdf because it is cached there and your colleague had a look at that cached file).
We can hardly debug that phone but we could analyze the pdf.
