A few ways of saving a recipe need your phone's permission before they can run. Tradish asks for these only when you first use the feature, and only for what that feature needs. Here is what each one is for, and how to turn a permission back on if you said no earlier.
If you have not used one of these methods yet, you may not have been asked for its permission at all. The prompt appears the first time you try it.
If you tapped "Don't Allow" earlier, the feature stays blocked until you turn the permission back on in your phone's Settings. Tradish cannot re-ask from inside the app once it has been declined, so this is a quick trip to Settings and back.
The names and exact path vary a little between iPhone and Android, but you are always looking for Tradish in your Settings and the specific toggle for that permission.
Each of these save methods simply cannot work without its permission. Scanning has no camera to read from, a voice memo has no audio to transcribe, and a photo upload has nothing to reach into. Turning the permission on is all it takes to unblock the feature. You can leave the others off if you never use them.
