What is the right term for "I have some issues new users usually have when doing something new"

When trying a new product / service, and having some "initial road bumps" when getting started, is there a term that describes this situation?

E.g. if I write to a support person - "Hi, I'm having some _______ when trying to ..."

I am looking for something other than "Difficulty", "Issues", "Problems", "Errors" and more of a "Stuff you usually get when trying something new", or even more accurately "Common issues every new product usually has and are not always the fault of the user".

e.g. I don't know if it is my fault or the new product has issues.

Is there a phrase / idiom / wording that conveys that?

Solution 1:

In computing, "teething issues" or "teething trouble" is commonly used in this context. Also, "gotchas" is often heard, for common mistakes.

Solution 2:

"Bugs" or "glitches" would work, although both are pretty informal. For example, "This product works well, but there are a few bugs that need to be worked out," or "I started using this product and I ran into a few glitches."
