Im really shocked that atlassian has a buggy product like sourcetree and since months nothing is changed (windows version but now even mac version). Even the beta discussion group is dead.
And the worst part? No communication from atlassian...
I noticed in other programs like bamboo similiar things... stil no offical java11 support - development is very slow but at least the quality is much better than sourcetree..
What happend to atlassian? If you cannot support a product like sourctree than stop it and remove it from your product line. No one will trust in your programs after using a buggy program like this with a sloppy development.
At least you have to communicate if you have problems like that (development member was gone - you are working on a solution...).
