InfoPath Dev

Is there a tutorial available for modifying task approval screen in InfoPath when using SPD 2013 workflow? I can't seem to find it anywhere on Google or YouTube. There are other tutorials available but not this one. Let's say there is a workflow which goes to line manager for approval. I want to design line manager approval screen in InfoPath. Secondly, as you know InfoPath EOL is July 14, 2026. What will happen after that? Will existing forms continue to work and no new update/patch will come OR existing forms will stop working all of a sudden?

I don't know the answer to your first question, I'm sorry. But to your second question, much depends on how you are using InfoPath and SharePoint. Are you using SharePoint online, or on-prem? Are you using InfoPath Filler or Browser forms? If you are using SharePoint Online, and InfoPath Browser, my assumption is that they intend to remove or turn off InfoPath Forms Services on that date, so browser forms on SharePoint Online won't be available. If you are using InfoPath Filler forms (i.e. everyone has InfoPath installed), I would presume you can continue using them until InfoPath Filler no longer works on Windows, and none of us can guess when that might be. If you are using SharePoint On-Prem, it looks like the subscription edition will have InfoPath Forms services removed at the same time. Oh, and you also need to be aware of the end of life for SharePoint Designer Workflows - If you are using SharePoint Online, these will be removed from existing tenants as of April 2, 2026: https://techcommunity.microsoft.com/t5/office-end-of-support-blog/support-update-for-sharepoint-2013-workflow-in-microsoft-365/ba-p/3796299
