Getting "The remote server returned an error (429)" when trying to deploy an app using Visual Studio

Just recently (past week or two), I started getting these errors when I am trying to deploy an app I'm developing using Visual Studio 2019 on my SharePoint online development site. I know it's not due to throttling from users since I'm the only one using the site. I usually have to wait a few minutes for Visual Studio be able to connect to my SharePoint online site.

Has anybody else been seeing this?

Skipping the uninstall step because the SharePoint Add-in is not installed on the server.

Error occurred in deployment step 'Install SharePoint Add-in': The remote server returned an error: (429).

    HTTP status code 429 means that SharePoint has received too many requests and the server is throttling your tenant. When a user exceeds usage limits, SharePoint Online throttles any further requests from that user account for a short period. All user actions are throttled while the throttle is in effect.
    A detailed article on SharePoint Online resource throttling is available with MSDN. These basics must be the same for SharePoint Server on premise too.
