You don't say.

Pasting an URL into a tweet entry form in their web client has been resulting in "Something went wrong" in 50% of cases for several months now. Attaching a GIF to a tweet randomly fails with no explanation given, again - for months.

I don't know what Twitter's development priorities are, but they sure as hell don't include proper web client testing.

Never got any of those. Perhaps you're using slow/unreliable network and hitting timeouts? Or some privacy tools interfering? Using Firefox web Twitter.

One thing I did use to repro though was text field behaving erratically on Firefox Mobile or when using installed PWA from home screen. Had to give up and use Chrome directly.

Twitter is a very mediocre tech company that thinks it's stellar and brilliant. Their product is consistently subpar, riddled with countless bugs, and they neither acknowledge it or fix it.

So yeah, no surprise that they would blame others for their failings.

The sad part is then, why is no one coming up with a better alternative?

But Twitter is a terrible idea so anything better than it doesn’t resemble it at all.

Then why are people using it? (I do not)

It gives them the feeling someone cares about their lifes

They are deeply entrenched. It's hard to move people to a different platform.

In fact seems to imply the opposite.
