I installed around 3 plugins for optimizing the website images and data because the website speed is low. For the PC version, it worked and is working fast, However, for the mobile version, the website is so low. Its performance in terms of loading speed is rated 60. I read in the internet and it says that the theme is heavy. Is there something that can be done for it ?
The second problem is that for the mobile version, the dimensions are not fixed, which creates a problem that the page is not stable. Here is an emphasis: https://snipboard.io/vY3NwT.jpg
