NDI for lower thirds not working with Proclaim

We currently use Proclaim for slides, confidence monitor and lower thirds for lyrics in our Sunday worship services. The NDI connection has been problematic at best. It will work for several weeks/months and then stop working. Sometimes restarting either or both of the programs and/or computers has helped. But currently after working well for about 3 months it has stopped working. This occurred following an automatic update on both Mac computers. Tech support for proclaim has advised that all settings look correct. We are running Proclaim on a MacStudio and OBS (along with ATEM switcher) on a Mac mini for streaming. I would like to figure out how to get this working with NDI or explore other options to connect via hardware. All other functions seem to be working correctly (camera inputs and primary Proclaim input through ATEM switcher).
