It could be triggering the same behavior, but it's triggered in a different manner. So I can't say it's a duplicate.
@jantanis can you try the latest build from the nightly package? (you can check Readme to get the nuget source where it can be installed from)
@AndreiMisiukevich I did with 1.1.0-preview1096, but no luck:
e.Action: Reset e.Action: Add e.Action: Reset e.Action: Add e.Action: Add e.Action: Reset e.Action: Add
I also have a problem in CollectionView! when i'm scrolling the LongPressCommand fires and the pressed scale remains and doesn't come back to normal!
should i create another issue or it'll be a duplicate?

Create a new one. I don't think this is de same issue as yours. Perhaps related, but a different issue.
This happens to more than just collectionviews. We add a longpress touch effect to all labels. All other (short tap / xamarins default tap) gesture recognizers earlier in the tree are not fired when you click on a label with a long press effect. If you need a reproduction scenario, please let me know.
