Linking to Dropbox on iphone

I installed Joplin on macOS and an iPad without issue and linked them to my Dropbox account. On my iPhone I can’t work out how to cut and past the Dropbox code into step 2 of the synchronise dialogue. Any all help appreciated

Hmm, yes I got the same experience too on iPod a few days ago. I think it’s due to Dropbox trying to be smart and messing with normal selection feature of Safari. I can only suggest to keep trying, for example by long pressing and dragging so that everything is selected. It’s poor UX but no alternative at the moment unfortunately.
