The slide stays white. One of the reasons why this may be happening could be your network setting. Click “Show content”, copy-paste the text and send it to your IT Department to add an exception for Slido. Text to send to your IT admin:Slido for Windows currently doesn’t support proxy authentication of any kind. The processes -- Powerpnt.exe, Slido.exe and CefSharp.BrowserSubprocess.exe need to be able to run and connect to the following domains in order for the Slido add-in in PowerPoint to function properly: *.slido.com*.sli.do*.sentry.iolog-api.newrelic.comlog-api.eu.newrelic.com If you’re using some type of firewall or proxy server, you must make the above mentioned domains to be accessed by the Add-in processes. The rules or exceptions would need to be configured using the domain masks instead of entering specific IP addresses as we use dynamic IP addresses. Sidebar isn’t loading and stays white (or shows an error) One of the reasons why this may be happening could be your computer policy set by your system administrator. Click “Show content”, copy-paste the following text and send it to your IT admin to adjust the rules. Text to send to your IT admin:If you’re using Microsoft Intune to manage the devices, the Attack surface reduction policy is enabled which blocks any Microsoft Office applications from creating processes. Also, Windows Defender may be blocking some parts of the Slido Add-in, too. You can adjust the Endpoint Security Policy to exclude Slido for PowerPoint installation path from ASR rules. Here are the steps: Open Microsoft Intune and go to Endpoint security In the Manage section, open Attack surface reduction Click Create Policy Use Platform: Windows 10 and Profile: Attack Surface Reduction rules Click Create Go through the wizard and configure the policy. Enter the path %ProgramFiles(x86)%\Slido\Slido for Windows in the Exclude files and paths from attack surface reduction rules policy. Save the policy and propagate it to your Windows devices. Note: If you are using the Basic installer, you must exclude the path C:\Users\*\AppData\Local\Slido\Slido for Windows in the above mentioned policy.If you need help or have questions, contact support@slido.com.  Sidebar is blurred If your Slido sidebar is blurred, it’s most likely because you’re using multiple monitors and there’s a large difference in their resolution scale settings. If Slido detects a difference >100% between your monitors, you’ll see the below message as a banner in PowerPoint:“Screens you use have different DPI scaling and the sidebar can look blurred depending on which screen PowerPoint is located.” For example, sidebar blurriness may occur on a 4K monitor screen scaled to 200% or higher when it’s connected to a HD laptop screen scaled to 100%Next steps:The quickest fix is to move PowerPoint to your other monitor where the sidebar is not blurry. Otherwise you can follow the below steps to adjust your monitor scaling:Open your Start menu Begin typing Display Settings and launch the application Under Scale & Layout, check the Scale value for both monitors Change the settings so that the difference in scale is less than 100% Restart PowerPoint  Sidebar says I don’t have access You man run into the below message if you don’t have access to the slido linked to a PowerPoint presentation. Messaging when you don’t have access to the slido This means that the presentation has already been linked to a slido that your current account doesn’t have access to. See the troubleshooting tips below:If you created the PowerPoint presentation, select Switch account and try using a different email address. It’s not uncommon for users to have slido accounts under both their personal and business emails.   If you did not create the presentation, select Request access to send a notification to the slido owner.    If you select Remove slido session, you’ll need to confirm your choice before the slido is removed from the presentation. Please note that removing the slido will also remove it for any other editors of the presentation.   Slido is not connected (upgrade to Windows 10) Slido for Windows will no longer be supported on operating systems older than Windows 10.
