No, not in normal replay mode, only in replay-pk (I'll try that later, didn't activate it yet it's off by default)But it should still be able to use the replay function...even in Wattage mode
For normal replay mode you need a temp wire, I guess that's why your blank box doesn't change, it only does if the coil is replayable.
Here's what my screen looks like (you can ignore the "Replay" on top that is the profile name I set manually, yours could be eg "Profile 1", it doesn't matter what the word there is it's purely based on a string you type in, don't be alarmed if yours doesn't show "Replay" there)
First one is before taking a puff (I think that's similar to what you're seeing), second one after taking a puff, third one after selecting "save puff".
I think it's just your coil material is wrong for replay, try with a SS, ni200 or titanium coil (if you have one).
