How to clear cache when using Google Slides as Data Source?

The above issue was filed 4 years ago. @ioannis has closed it without any resolution. Let me explain my issue.
I have 2 screens, Scn1 and Scn2. In Scn1 I access information from row 1 - row 5 and write it to Label-1 - Label-5 using google slides as the data source. I switch to Scn2 and switch back to Scn1. I repeat the same operation I did earlier, but this time the row 5 value is being repeated in all the labels. I think that the last read value is being cached. In the above enclosed bug report from 2020 the user is facing the same problem. Please suggest a fix.
Also note that when I was coding I kept getting Thunkable internal error. So I feel that there is a fundamental flaw in the “get row object from…” block.

Try putting a


as the first block in the function Eng. set app varaible LangObj = create object. That might clear the cache. Please note when I tried to code this it kept saying Thunkable Internal Error, contact support. It did work though. I wish Thunkable was bit more specific about the error than just a generic Internal error message.

Setting the ‘LangObj = create object’ made it work for the first time. That was the only change. When I did subsequent operation it failed again. I tried setting the LangObj = create object whereever possible but the cache did not get cleared at all. So I finally gave up and resorted to a different methodology. Thank you very much
