What Gamma users complain about — and what SlideDeckMaker does
- PPTX export shifts layouts, puts each line in its own box, or turns slides into images
- Statistics without sources — often wrong when checked
- Analytics, brand fonts and custom domains only on Pro ($25)
- Indic / Unicode PDF font embedding incomplete
