Therefore I asked if it is Samsung! Samsung can everything except software! 😚

Then setting the control type to platform should work, as I have mentioned.

Happens that only in Delphi Apps? Then try to set the control type to platform for the edit. When it happens in all apps, which smartphone do you use? Samsung?

Is 32 / 64 bit matching between your app and webview?

Try a Select Sum(Round(Price * Qty, 2)) as Total or Select Round(Sum(Price * Qty), 2) as Total And what is the FieldType in ClientdataSet?

Try Bitmap32 from https://github.com/graphics32 TBitmap is not Threadsafe in most cases.

Is at this place something filled in "restResponse1.Content"? Is the value later (after the Handler) filled? And what is the StatusCode of the response?

In case of ExecuteAsync, have you used the ACompletionHandler Parameter instead of the Afterexecute event and also set the ASynchronized Parameter to true?

Instead of creating your own thread/task, you could/should use "RestRequest1.ExecuteAsync(...)".

Do you use a DLL and have also in Windows event log something with "KERNELBASE.dll"? I could only solve such an issue by including the DLL code into program.

Download works out of the box, upload not. You must have a PHP Script, a CGI, a ISAPI dll or an own server to be able to upload files.

What did you install / configure on Apache server side to accept uploading files?

Not much information. I would also create a logging in the ISAPI dll.

Not sure, my experience with IIS is a long time ago, but it could be here: %SystemDrive%\inetpub\logs\LogFiles

Are you loading DLL's or other files you expect in root folder?
