Promise Returns but busy stays..
Busy stays and blocks the UI even after the promise returns..
app.module.ts `import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { FormsModule } from '@angular/forms'; import { RouterModule, Routes } from '@angular/router'; import { TreeModule } from 'primeng/primeng'; import { BusyModule, BusyConfig } from 'angular2-busy'; import { HomeComponent } from './home/home'; import { ProductsComponent } from './products/products'; import { TechnologyComponent } from './technology/technology'; import { LocationComponent } from './locations/locations'

Unfortunately I also have the same problem.
Below is the version I currently use:
"angular/animations": "^5.2.0", "angular/common": "^5.2.0", "angular/compiler": "^5.2.0", "angular/core": "^5.2.0", "angular/forms": "^5.2.0", "angular/http": "^5.2.0", "angular/platform-browser": "^5.2.0", "angular/platform-browser-dynamic": "^5.2.0", "angular/router": "^5.2.0", "angular2-busy": "^2.0.4",
I have the same case, no logo to have it removed in loading after the Promise returns catch
