Can I use IDE Settings Sync in fallback version?

Hello,

What is your fallback version?

My fallback version is 2018.2.

IDE Settings Sync plugin is supported in that version, so it should work fine. Do you face any issues with it?

Sorry, my mistake.

Can I use IDE Settings Sync plugin in perpetual license version?

Plugin is supported since 2017 version. I guess your perpetual license version is 2017.

I've purchased 1-year subscription of 2018.2 Ultimate so I have 2018.2 perpetual version.

I'm wondering does the plugin also work in perpetual license.

Yes, it does.
