TTMSMQTTClient Performance Problems with Version V 2_0_2_0

We used version v1.3.1.1 in our software products.
This version worked well and quickly.
After updating to version 2.0.2.0 we have performance issues between Subscribe and Acknowledged.
After downgrading to v1.3.1.1 everything is ok again.
We use RadStudio 11.2 Patch 1 , FMX Delphi App (Android, Windows, MacOS, IOS,)

Can you please provide a sample so we know how you use the component?
We've tried to reproduce this issue with several brokers, component configurations and operating systems without success. The FMX demos run fine on Windows 10 and Android 11.
Maybe this is due to some event handler code in your app that takes up time?
