Ltex LSP spamming progress notifications

Language Server Protocol (LSP)
1

I recently started using the ltex-ls LSP and it seems like it runs the check after every single character I type, which results in many progress notifications appearing as I type (see below). Is there a way to change this/limit it, or is this a bug?

Have you been able to solve this issue, I have the same problem in my markdown projects

Same issue here.
I was able to fix it by changing the checkFrequency from edit to save:

require("lspconfig").ltex.setup {
  on_attach = require("lsp-format").on_attach,
  settings = {
    ltex = {
      checkFrequency = "save",
    }
  }
}
