Hi Se,
Please take my apology if you feels bad.
Actually, opening a new question for separate user is good, so that we can check issue in your backend too if needed. If you post within another post, we do not recommend to include sensitive info other than own post.
For your other question, as we all know, Joomla 4 is still a new thing, so we are trying to make our products compatible with this new update. In this process we have to update many component versions, such as bootstrap, fontawesome and many more. You might know, bootstrap has changed breakpoints and many default CSS, which may look like update changed your site appearance. So, we are not responsible for each and every changes, actually. Moreover, some things happens only under some specific/special environment. We check our products with normal environment, as it's not possible to check with each and every third party extensions. At our end, most of the things works in this way. This is the reason, we are asking for your cooperation to check the exact thing that our users faces time to time. Yes, we all have mistakes, and we are trying to improve day by day, it's a continuous process. We really appreciate valuable suggestions of our honorable customers.
Have a nice day!
Best Regards
