My websit doesn't work on metamask browser

Hello support team!
Hope you are going well!
As a blockchain developer, I’ve developed a website and I use metamask google extension on my pc.
In a word, the site works fine on the pc.
But When I tried to open the website with metamask browser on my android phone, it doesn’t work.
My site url: https://stixex.io/

My issue is following:

View: BrowserTab
TypeError: undefined is not an object (evaluating ‘(0,r(d[14]).weiToFiat)(p,l,u,2).toUpperCase’)

==========================================

I am looking forward for your reply.
Best regards

Alex
