Please help me re-word this sentence [closed]

Question

I'm having a hard time formulating a sentence with the following meaning

Please note that not all eBooks support all the different platforms and devices.

I think the sentence conveys the idea (please mention if it's ambiguous); however, I feel it's unnatural and unprofessional.

I'm looking for suggestions to re-word and improve it. Thank you!

Answer 1

Please note that some eBooks may be unavailable in formats required by certain eBook readers.

• First off, the relation is in opposite direction. Device supports media, not the opposite.
• It's about formats, not the content so, eBook formats.
• A device supports a number of formats, requires any single of them.
• an eBook reader covers both devices and programs; mostly all platforms support all formats, providing they can run a program that can read them.
• not all...all is less than optimal style. I think "some, certain", "unavailable" is a better word choice.
• I'm still not sure about "certain", you may prefer something like "selected", "chosen" or such.
