ggtern will not run with the latest ggplot2

[Knighty16]

There seems to be an issue with ggtern running with the new ggplot2. I have tried to load earlier versions of R, ggtern, and ggplot2 but cannot get them working. With the latest versions I get the following error:

Error: geom_point requires the following missing aesthetics: x and y

rlang::last_error()

I am facing exactly the same issue while I am trying to correct a plot that I have already generated using previous versions of ggplot2.

packageVersion('ggplot2')
[1] ‘3.3.5’

packageVersion('ggtern')
[1] ‘3.3.0’

The following are appeared:

Error: geom_point requires the following missing aesthetics: x and y
Run rlang::last_error() to see where the error occurred.

Same error for me

I found the version combinations to get ggtern working again is:

reload:

R 4.0.2
ggplot2: 3.3.2
ggtern: 3.3.0 - ignore the warning...

Kind regards
