Hi Sara
I have my webserver app based on the fabulous RNT webserver tutorials all working brilliantly in Chrome, but one component does not work in iOS Safari. I have been using  javascript instructions with  localStorage.setItem and localStorage.getItem to change and keep some user (me) selected colour choices from a colour picker, but these code lines result in blank saved colour panels on my web page with current versions of iOS and MacOS Safari. My web searching conclusions are a bit confusing as to whether this can be overcome or not. I do not have cookies blocked in my Safari preferences which is suggested as the cause in some “answers”.
Are you able to advise me if this problem can be overcome or do I just need to delete this capability from my app? Thanks in anticipation of your advice.
