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?
