I just tested this and it works fine. I displayed in a browser window that had no authentication to the account and it merely offered me to get the app or continue with browser. No problem at all, had the file a moment later.
This is user error somewhere in the process.
P.S. free account used.
P.P.S. Tested on iPhone share link from Dropbox app to clipboard, paste into two browsers: Aloha and Firefox. On both I got the standard cookie notice - which I DECLINED and it wasn’t a problem. Then the screen offered get the app or continue in browser. Chose browser and my file came up. No problem whatsoever.
OP refused to take advice and troubleshoot, instead just rants with baseless accusation. This is not a behavior I haven’t seen countless times already.
That’s not how software works, dude. Programs are a series of precise instructions, and a computer will always follow what the instructions say, exactly, unless something interferes.
There’s no luck involved, ever. Luck is also an imaginary construct.
It could be a variety of causes on your end, and I saw many people make suggestions to you as to identifying and resolving the problem, but you refused all of them.
You want to hate Dropbox and you want others to join you. I do not know the reason, but this is the only conclusion available based upon your behavior.
We are here if you are willing to troubleshoot to achieve the results you desire.
