I bought a license for poedit pro+ and wanted to use it on openSuse Tumbleweed. The instructions stated to go to File > License, but I could not find it. After some searching I found that the pro version was not available on the open source version (the one I had installed with zypper) and I had to install it from Snap.
You can follow the steps here to install.
I don't know why, but
poedit does not run without
snap install snap-store poedit
