KDE Connect applet is missing from the tray I can't see it in System Tray Settings list of applets either.
Cannot reproduce on Neon Testing, Plasma 5.93.0, Frameworks 5.249.0, Qt 6.6.1 What distribution are you using, what desktop and version # of desktop? If you're using Plasma, what Frameworks and Qt version are you using? If you are using Plasma, that will be in System Settings under "About this System"
Operating System: Solus 4.5 KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.249.0 Qt Version: 6.6.1 Kernel Version: 6.6.15-272.current (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 PRO 4750U with Radeon Graphics Memory: 29.1 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: LENOVO Product Name: 20Y1001SAU System Version: ThinkPad P14s Gen 1
Is your kdeconnect compiled with Qt6?
Sorry, my fault, I thought I'd updated all my Gear apps, I must have missed KDE Connect. After rebuilding with Qt6, it is working.
