Issue with texting in Spacebar on Pinephone Pro

Spacebar reports “No MMSC configured.” Texts do not identify by name from the Phonebook, but rather are identified by number. One good thing is that group texts do list the numbers of the recipients. I’m using Plasma.

To add to this further, I see that texts within Spacebar are identified mostly by number now rather than name. A while back, names were obtained from the contact list which the app Phonebook provided. That seems not to be the case now (or, it seems more sporadic than it once was).
