I have a shiny app that runs fine on my computer. I use packages sf, leaflet, and tmap. One of these requires the package lwgeom as a dependency. While installing the package lwgeom, shiny deployment gives me the following error message. What is GEOS? And how can I upgrade GEOS to 3.6.0 or later?

Update: I notified shinyapps.io and after several weeks they upgraded to to GEOS 3.8.0. So, now my app deploys fine.
