I have tried to Copy paste a column for nearly 30 mins!!! You’d think something so simple wouldn’t take more than 2 seconds, the only thing that seems like it would be similar to copy pasting a column is the V-look up app, I come to the community to see if there was something that I’m missing, however, when I looked at the past discussions I noticed that, people have been having this issues for more than 4 years!!
Are you trying to ‘paste’ it to another board or the same board? If ‘another’ board, you’ll want to look at ‘Connected Column’, if same board, then you’ll want to use the ‘duplicate’ option.
