I loved this app until bug – Mega Photo: Real-Time Effects Review

I loved this app because of the stickers feature. I would make pngs and make custom stickers. But now it seams that the custom sticker's feature doesn't work with pngs any more :( plz fix this bug ? so pngs work in the stickers section. Thanks - a loyal customer
