Phpls premium features are not working as expected

Describe the bug When I try to find all implementations of interface/abstract class within a project that was just indexed everything works. If I close neovim and open it again nothing works until I run the command intelephense.index.workspace. I made sure that I have no global intelephense module installed on my machine to avoid any conflicts. The current up to date version of intelephense is 1.5.4 while coc-phpls is using 1.5.2 (which I assume is installed with the extension as a dependency) so only the dependency that comes with the extension is available. I also tried it while there is a global module installed and I have the same issue. I have a premium subscription to make sure every premium feature is available. Note that the premium subscription works when using visual studio code.

To Reproduce Steps to reproduce the behavior:

1. Open a php project for indexing for the first time.
2. Try to find all implementations of any interface or abstract class you can see that you will get a list of all of them.
3. Close nvim.
4. Open nvim again and open any php interface again then try to find implementations again you will receive a message [coc.nvim] implementation not found

Expected behavior To be able to see all the implementations and the premium features working as expected

Desktop (please complete the following information):

• OS: MacOS 10.15.7
• Coc.nvim (the latest version)
• Coc-phpls extension (the latest version)

I still do have this issue. I use VIM 8.2 and still cannot see any implemantation even after creating the file mentioned here.

thanks.

I’m having the same issue. Managed to get it working by placing license key in the {os.homedir()}/intelephense/licence.txt
