Issue GTranslate on mobile browser not working.

Dear Sir,

On this website: https://ark.santhoshhn.com I have added Gtranslate plugin. It works fine when I change the language to Arabic or English on desktop mode and try to access inner pages go back to previous page the language remains which I selected. However, the problem starts when I do the same on mobile. If I toggle language to arabic and tries to go inside pages and come back to previous page the language automatically changes back to english eventhough the language still selected arabic. This is really annoying. I am seeking for help by the developer of this plugin or anyone who has fixed this bug in the past please kindly respond.

Elaboration of issue with screenshot provided here

Question: Do I need to press the back button on the browser or just navigate to the previous link?

Yes, on the browser: https://prnt.sc/Pe1tAJGodqzL
When we click on the back button, the language turns back to English, even though the language still selected as Arabic: https://prnt.sc/w2PmW45beBlo
It should remain Arabic. Request you to kindly check on this and let me know the solution to fix this.

Regards
San
