Hi,
We have added a new version of LVGL to SLS and forgot to use Ubuntu 18.04 to build. Sorry for the inconvinience…
Please extract and copy micropython.zip (1.0 MB) to SquareLine_Studio_Linux_v1_1_1/lvgl/lvgl_v8_3_3/server
. If you confirm it’s working well, we will update SLS v1.1.1 with the new server.
