@coopey Almost certainly the browser engine. The stock Sailfish browser runs quite an old Gecko build, and Kwetter is built as a responsive web app targeting modern browsers. Still curious what exactly broke though: blank page, broken layout, or the composer eating your input? Helps me see if it's Sailfish-only or something wider.
@mexxus I know, the browser is awful for anything other than reading text on a static page. Was surprised it was still so bad on the new model after a few years away. It had a mad moment of not accepting the correct input and just adding a few characters. No pattern, other than them being lowercase letters; post just looked like ‘hhhgkkghhgk’. I’m no expert, but confident it was a SFOS issue.
