To save sessions to your schedule, use your www.asha.org username and password to log into the planner or app, then select the black calendar icon that appears next to the session title to add it to your schedule. The Program Planner and the mobile app sync, so if you save sessions to your schedule in the planner, they will also appear in the app if you are signed in, and vice versa.
Installed plugin but just get an error Resources/plugins/FlywithLua/scripts/asha.lua:62: attempt to concatenate global SYSTEM_DIRECTORY (a nil value) on starting flight and Lua stops. Hope this means something to you. I am using 11.50 with Vulkan and attach the log.txt and flywithlua_debug.txt
