The answer to this question is yes and no. Yes, it is possible for a Progressive Web App (PWA) to be compatible with all devices, but it depends on the specifications and capabilities of the device. The technologies used to create PWAs are designed to be platform agnostic, meaning they should theoretically run on any device with a modern browser.
However, certain features of PWA web development may not be available on certain devices due to hardware limitations or lack of support for specific standards. Additionally, the experience and performance of PWAs can vary significantly depending on the device in question. Therefore, it is important to test your PWA thoroughly on  any target device before launching it.
