Hi @Kavya,
Sorry to hear you’re experiencing trouble with this.
Please take a look at this post and see if it helps.
Additionally, could you possibly let me know if this issue is affecting both the frontend and backend of your website?
If it is specific to the backend, please provide me with the breakpoints you have configured for tablet and mobile view, which you can find from the Global styles > Settings > Defaults.
Thank you in advance.
