File writeFile don't save Blob on some Android

Hi guys,

I have a problem with saving blob to my android device via cordova-plugin-file writeFile method. There is no problem in iOS and some Android devices.

async downloadLogbook(vehicle) {
    try {
      const data = await this.logbookProvider.getLogbookPdf(
      const blob = new Blob([data._body], { type: 'application/pdf' })
      const filename = 'logbook.pdf'
      const opt: IWriteOptions = { replace: true }

      await this.file.writeFile(this.file.dataDirectory, filename, blob, opt)
    } catch (err) {

method writeFile is not returning anything. No err, no Success

Any idea?

@anespa Can you tell me the right procedure, please?

As you said in index.html at /src i just put the polyfill.js file inclusion above the cordova.js file inclusion.

Thats all.
