Hey everyone, thanks for the comments. The new long press gesture to bring up menus & previews like this is actually a part of iOS 13, rather than our apps in particular. If you move the action as soon as you pick it up, then you'll be able to drag it around, but it is tricky to get that right.
We hope that more tuning will be possible in the future, but you can make it less sensitive in your settings under "iOS Settings → Accessibility → Touch → Haptic Touch → Slow".
Changing this setting gives you a little longer to move the action before the preview opens, and will help in all apps that are making use of this new iOS 13 feature.
I hope this helps! Please let me know how you get on :)
