Since the last application update (it feels like it) Dolphin has been behaving strangely when trying to copy to linked folders. E.g. Pictures here with my system.

Images -> smb4k / DATA.TUX.LAN / Images

if I want to copy something there, dolphin always wants to overwrite the entire order. Can any of you understand this behavior? Here the picture:

Plasma 5.18.5, Dolphin 20.04.0.

Thank you very much

Confirmed!
I have most folders in my home directory as symbolic links from /data partition.
Copying a file to such folder results a dialogue stating that the target folder name object already exists and asks if I'd like to overwrite etc the target...
Well - this is very dangerous situation as if you don't pay enough attention to that dialogue, then the entire folder gets deleted and a new file you copied with the name of the now previous folder is created ...
It was OK in previous Dolphin and I do not see such behaviour in Mageia Cauldron Plasma 5.18.5 and Dolphin 20.04.1.

Fixed in KF 5.71 to be released June 13th and also quick fix kio-5.70.1 is ready but seems that not yet in KDE Neon User Edition.
Is it related to that we still have not got KDE Apps 20.04.1?

Ok. Clear. And maybe for the Apps Updates.

Works now after update in Neon again
