Turkish Airlines has quietly extended Miles&Smiles members elite tiers by six months.
The airline has not sent out any communication to its members about this extension, and there is no information on Miles&Miles website. You can see the extension when logging in to your account.

There must be communication coming out from Turkish Airlines Miles&Miles members in due course, although this is one airline lacking in the customer service and comms.
Airlines have extended member tiers from 6 to 12 months. I would say that the latter is more appropriate consider how long it is going to take to get air travel going again.
