I'm using v12.7.1 (most recent available on apple app store) on an iPhone 12 mini running 15.4.1.
Joplin works fine on my mac and iPad. On my phone I can get the initial Welcome to Joplin! along with the other four initial notes. I can set up my configuration. I can add an initial note. THEN it breaks ... all I get after that is a white screen, a thick black line at the top, and nothing else.
Any suggestions? Some setting in the iOS maybe?
