I have premium but cannot use all the tools. – Prisma: Photo Editor, Filters Review

I have had Prisma unlimited subscription for years and recently cannot use all the tools, HD and the ability to adjust from fully filtered to less filter applied are gone. I can’t find tutorials on the app. It’s fun, but not as good as if I had all the tools available. This happens with all types of pictures, not just portrait. Am I expected to go up a level to premium?
