We have 30 years of browser UX development, culminating in tabs and multitasking tools that allow you to open things to read later, wait while they load on a slow connection or form a queue of things to read.
Mobile apps for every social media site loose all of that. They are worse than useless. There is this internal fear at social media companies, they want to prevent their users leaving their little walled garden. That or the religious drive for managers to reach target metrics creates a net negative feedback loop for user satisfaction.
Social media apps have no multitasking features (at least last time I used them). It's absurd.
I've only used the twitter mobile website for the last three years. Will never install the app again.
(Aside: my (ridiculous) conspiracy theory is that React Native is an attempt to distract developers from the advantages of a WebView based app development process that would eventually lead to the success of PWAs, locking devs into the app stores as a distribution channel)
