Sadly it won’t happen any time soon.
ETFs (and their manufacturers) are required by European law to create certain legal disclosure documents for retail investors to have sight of pre-sale.
Most US ETF providers have little incentive to jump these regulatory hoops for sale into Europe so simply don’t bother.
Without this/these documents they can not be legally sold this side of the pond.
There is often a dispute about whether or not this position will change - but so far (to the best of my knowledge) no one has managed to find a loop hole or work around. (With the exception of Abra who technically/legally makes you a synthetic so you don’t buy the actual share).
Your best bet is to buy the underlying holdings or hope that an iShares/vanguard/Boost/WidomTree/xTrackers/DWS/Lyxor (or any European ETF producer) sees sufficient business here and provides a similar product. However they may not legally be able to because of various European States’ laws. No provider wants to run the risk of reputational damage… yet.
