The Articles are now treated in Anglicanism as historical statements only, and with the possible exception of Sydney Aus. (deeply evangelical) and a few places in Africa, hold very little purchase. As to Transubstantiation, I don't mean to be disrespectful, but I had to laugh. A gazillion RC worldwide take communion regularly, and couldn't explain the dogma if a billion dollar prize was on offer. I suspect many of them would not affirm it it if they knew about it, in any case yet we are called upon to affirm it?  Besides it is one explanation for Real Presence, not the only one.
