First time triathlete

Hello and welcome!  It can seem overwhelming at first, learning the ins and outs of this new to you sport.  Something I feel is important is to be patient and reasonable in your expectations of yourself.  New skills often take time for one to become adept at, and here's where the patience comes in.  Especially when learning a new skill, gains will come gradually with time and consistency of training.  Good luck to you!  There is a UK user forum if you haven't already found it.
