I didn't see if you mentioned whether this problem is on 50 or 30 amp service.
Have you been in any areas where the debris from trees will clog a coil?
I've never been, so don't know what trees they are, but I've seen pictures of AC coils that look like they are covered in raw cotton.
We also have a 2019 39DBRS3, with the 3 AC's, and I'm glad we do.
If we are on 30 amp the load management system will dump the 2nd AC compressor if anything comes on while running. If the extra load ends soon enough the compressor delay (2.5 minutes I think) will bring up the hour glass symbol.
This is with 2 AC's running. If I try and run 3 the load management will dump the first 2 anyway.
If you can do the add on, the third AC is a real benefit in the heat.
On 'good' 50 amp service in 95+ temps we can keep the inside around 72.
On 30 amp though we are lucky to keep it around 80 with only 2 AC's and one kicking out as loads vary.
