I installed the 2023.2.1 Preview 1 yesterday but it's not available in Launcher. All i have is a new 2023.2 Preview 1 desktop icon (screenshot attached below).
Also when i open 2023.1.2 there's a message to update TM to 2023.2.0 (see last image below).
Previews do not stay inside the launcher, only the latest will be visible. As for the message to update, don't worry about this. This is being fixed now and should not affect your project.
Please review the plugin page to be sure to use the right version for Sketchup 23 and Wind 11 should not affect Twinmotion.
My issue is that i've installed Community Preview 2023.2.1 like all previous updates but there is now no reference to it in the Launcher , only a Community Preview icon on the desktop.
