Unacceptable update frequency of 10 minutes

Installation of my system, done by SolarElectirc (Noordhoek) was done excellent, including all paperwork. The system is running fine. However . . . . . Soon after installation the update frequency of my App went down to 5 minutes instead of the 60 seconds I was told it would be. SolarElectric contacted Sunsynk but the update frequency did not change. I contacted Sunsynk directly multiple times and I always got the message that "the provider" was making essential changes to the database structure. This has been going on since January 2025 and on top op that my update frequency was set to 10 minutes! In my view 60 seconds is rather slow but ten minutes is absolutely unacceptable. Contacting the CIO Joel Egan did not even result in an answer.
