Ikea Dirigera?

After updating the Diriger gateway, I’m experiencing significant delays in the operation of ZigBee devices connected to the Matter bridge with Smart Home Hub 2 (Aotec Hub v4). Automations created in Smart Things sometimes work fine, sometimes with significant delays, and sometimes they don’t work at all. I previously had an Aotec Hub 3, and today I bought an Aotec Hub v4, and it’s still the same. Everything worked fine before. Do you know anything about this? I contacted Aotec technical support, and they told me to reset the router, Aeotec hub, Diriger gateway, Aqara Hub E1, and Matter Sonoff MINIR4 switches in the correct order. It helped for a while, but then the delays started again. I don’t know what’s causing this. I first suspected the Aeotec hub because I also experience delays with Matter Sonoff MINIR4 switches after using SmartThings (it works fine in Diriger). For example: I open the door, and in SmartThings, the sensor status changes with a delay of a few or several minutes (in the IKEA app, it changes immediately). Is it possible they broke something in the latest Diriger update, or should I look for the problem elsewhere? I should note that the problems started after updating the Matter bridge to version 1.3 (October 27th). I wrote to IKEA a few days after the update, but they haven’t responded
