Unable to gift data

If your data is a rollover you cannot gift them. Also you cannot gift them 48hr before the end of the cycle bill

Did you try gifting smaller amounts ? Like the previous poster wrote, you can't give rollover data nor 46 hours before end of cycle.

I've had issues with this as well, but after trying several times it eventually worked for me.

I can't gift my current data, either. So it's not just a rollover issue.

I cannot gift any data at all.

Maybe it's just a new bug.

The first answer received from Mike seems the way to go.
If that does not work, contact Fizz via Facebook messenger to see what the problem is.
