I suspect that many/most PDs will suspend LTC apps/renewals. They can get away with it and use the virus/emergency as a convenient excuse. IIRC courts are shut down for a month or so and therefore if you sued, the hearing would probably be scheduled for 2021 or 2022.
MGL specifies that you CAN Mail it in, doesn't require an interview either. If they were truly concerned about "serving" (that's a joke), they would notify that you can mail it in for renewals and they would process WITHOUT any interviews to minimize exposure.
