AIAG, EMQP, FSKY, ISPY, KLWD, and ROBG will soon be available only to ‘Plus’ customers (see discussion here). EQGB and EQQQ aren’t on the list of Plus-only ETFs yet, but they are Invesco ETFs and the intention seems to be that free customers will only have access to iShares and Vanguard ETFs, so they might be at risk of being dropped too.
So, of the ETFs listed in the posts above, that leaves DGIT, RBTX, and IITU available to ‘free’ customers, as well as one new one which has just been added: CNX1 iShares NASDAQ 100 UCITS ETF USD (Acc.).
