Cyrillic fonts not working in Adobe Portfolio

Hello! I downloaded some Cyrillic fonts to my Creative Cloud apps and they work on every app except Adobe Portfolio. I tried writing with a Bulgarian and a Russian keyboard but they never seem to work... even the Standard fonts! I read that Adobe Portfolio now supports Russian but I guess it doesn't apply to the fonts... Can someone please help me with fixing this or maybe help me find some Sans serif fonts with rounded edges for Bulgarian and Russian?
