Dreame A2 mower after latest firmware update loses WIFI connection with the app

I purchased Dreame A2 a year ago. It worked well in 2025.
In March 2026 I took it out and turned it on after winter break - it updated firmware - and all was good with connectivity. But later in a month there was one more firmware upgrade. One of the improvements was - Wifi connectivity fixes. As a result, now I cannot normally manage my A2 mover remotely - cause it looses WIFi connection.

So, please either release a fix or suggest how I can roll back to the previous firmware?
Current firmware 4.3.6_0550 - broke WIFI connectivity.

The same issue happened in 2025. There was a firmware upgrade around JUNE 2025. It broke the Wi-Fi connectivity with the robot and the app. It was fixed with the next firmware that came out within 2 months.

My previous posts from past year about similar issue with A2:
