Hello @pmginvestda6z
I understand that it is frustrating, and I am sorry for the trouble caused by these issues.
Your previous post was on a topic that we have provided a solution for, and the best way to get a response fast is to create a new topic for your issue, as you did here.
At the moment, I am still trying to replicate your issues on a new Thunkable project.
For the Base64 issue, here is the image I used and it worked:

Also, could you please share the project that you have the performance issue?
This way we can investigate it further.
