There are 25 ETFs in total available from Vanguard in the UK. Some of them are already in the app, we are talking about no more than 10 that need to be added. I don’t understand what is the problem in just getting all of them in the app. It is tiring to have to inquire, vote and comment every time for the different ETFs there are from Vanguard. Just add all the remaining ones and get it done with. In particular their bond funds, but I don’t see a reason in adding only them.
