I mean, LinkedIn was always bad, but what changes were you talking about? I can't recall noticing anything different on the site in nearly a decade. Only thing I can think of is the ability to accept all invited.
They used to have a good native iOS app back in the early days. They now replaced that with an Apache Cordova or React Native app (actually it’s probably too shitty to be a React Native app).
It is the worst pile of shit I have ever used. I’ve used non-native apps like that before but this is the worst I’ve seen so far.
And of course, the app has the usual dark patterns around trying to get you to share your contacts, add a photo (there’s a persistent banner at the top of the feed asking you to add a photo and follow some “sources” - hashtags full of spam that is - even though I’ve had the account for 2 years now so they clearly should know I am not going to do any of those things no matter how many times they ask).
