Fix broken share extension animation

[bcutter]

When adding a link using the share extension, the only visual feedback is a white box (which actually technically is a black box because you have no valid response of what is going on - successful? Unsuccessful? Nobody knows):

See for example Frigoligo app with first a white box and a progress indicator, few moments (1 second) later the confirmation animation:

Hi,

Thanks for taking the time to report the issues you’ve encountered.

Just a quick reminder: this is an open-source project that I maintain in my free time, and lately I haven’t had much of it to dedicate to the app. I totally understand your frustration, but please keep in mind that development and fixes may take longer than expected.

You’re, of course, free to stop using the app if it no longer meets your needs — that’s entirely your choice. That said, constructive feedback, clear bug reports, or even pull requests are always welcome if you’d like to contribute.

Thanks for your understanding,
