I took the Leave Request template app and modified it to use it for our company. The application was tested thouroughly and then released to a couple of teams. Now, the canvas application doesn't open and the spinner keeps spinning, nothing happens. No errors or anything. It just keeps spinning. This happens only if I open it in the browser. It is working fine on the phone though.
I haven't changed anything and published any new version. When I republished the app a couple of times by just opening the application and inputting a space or remove a space, it works for sometime and goes back to the same issue. of course, it works fine when I play it in the dev and edit mode. Its only the published version which seems to be so unstable. I see no errors. I don't see anything obviously wrong with the application.
I thought may be I'm using some custom connectors. Here are the connectors I'm using. I'm not aware if any of the following are custom connectors.
Sharepoint connector for 5 lists
Office 365 connector
Connector to invoke a flow
Does anybody have the same issue? or I'm not seeing or understanding something?
With the licensing issues related to custom, premium connectors, and the issues related to delegation it is a very frustrating experience to develop an app in power apps, even though I like the development experience itself.
