Signature background turns black on iPhone and iPad
Hello
I've been using acrobat reader as my main PDF application for a while, but after a glitch I had to reinstall the app on all my devices. Now I can sign and stamp documents easily on my Mac, but unfortunately on iPhone and iPad signature and stamp background instead of being transparent turns black. I use the same image file (PNG) on all devices.
Can anybody advise what is the problem ?
Thanks
