Unable to find some tags in Steemit

Hello Steemians.

While trying to find out some topics like "bangla" , "chess" etc. I am not getting it under tags. I am scrolling down form all tags and clicking on "view all tags". There I am trying to find my interested topics by using ctrl+f.

It is not that those topics are not tagged under which I am trying to find. I have already read posts which have used "bangla" in their tag but during trying to find from all lists from "view all tags " are missing.

So any body who have faced similar issues or who can give any solution to this please reply. It will be a great help for me. Any additional information will be highly appreciated.

Thanks with Regards
