while testing with dummy projects and clips, copying multiple clips then pasting them sometimes work (like 1 out of 10), most of the times it just paste only 1 clip .
using production files (with more layers and instances), it's now nearly impossible for me to copy/paste multiple clips using tvp 11, either within a project or from one projet to another project. It only paste 1 clip out the the selection, see gif below :
(this used to work fine in older tvpaint versions 10.5 and early 11. since 11.5xx, copy/pasting clips is very unreliable for me, making project management very tedious (merging and splitting storyboard files)
