Copilot says it is working on Finalizing but it never completes, waiting all day.

I have had the following experiences of using multiple AI tools in last say 12-18 months

1. I gave the Co-pilot almost 34 pages of content in 4-5 lots. I only asked it to remove the duplicate - what it showed was a version of its own in just 4 pages - when I pointed out, again, it gave content of less than 4 pages - after 10-15 tries, I gave up [even after giving it small bits - it deletes without any logic - this I tried with different types of content almost always same results
2. Then, since the last couple of months, I have been giving it articles that I post on my websites as well as on FB, LinkedIn, and Medium - to organize - sometimes it takes 4 days to give, and sometimes it never happens to give
3. Yes, it assures very well and apologizes fantastically.
4. Compared to GROK, it gives answers without limit, AND if you are lucky to catch DeepSeek when it is free and can tell it very clearly, it gives good quality content - GEMENI also gives detailed answers and helps
5. I use AI tools only for clerical work, and doing research and referencing, because creativity, the Gen AI will take time to be mature enough to actually give you something original
6. Sometimes I cross-check the same data, taking the same content and posting it on several AI tools, as at times I realize that the Data or the info was not exactly right

This is pretty standard behavior in my experience. I'm using the Copilot desktop app on Win10 and quite frequently it tells me to hang on and it will get back to me. The operative word here is "hang" because it never returns voluntarily. I've usually gotten it to return by typing something like "Please provide the results now.", and if it again tells me to wait I merely repeat my request until it either gives me the results or tells me to change the topic.

I don't know about PowerPoint specifically, but since I've been using Copilot's "Think Deeper" mode rather than "Quick response", I never had the "eternal wait" issue again. Like "Quick response", "Think Deeper" is also free and provides unlimited interactions. One thing I still find extremely annoying with both of them is that Ctrl+C does not work correctly for copying, although you can right-click on the highlighted text and select "Copy" from the resulting context menu and that will work. They should either fix it or remove Ctrl+C from the context menu. Ctrl+C does work correctly with the various versions of Gemini 2.5. Gemini 2.5 Flash is free and apparently unlimited.
