Ipad with IOS 9.3.5 connection issue

I just installed OSC V1.9.7 and created a server on my PC. When I try top connect with an old IPAD (IOS 9.3.5) I can connect using the http address, but I see no button. I have saved my template and it is loaded on my PC (server). But I don^t see it in the Ipad. When I try with a new Ipad, or with an Android, it works and I can see the template. Can someone help me.

Hi,
It may be an old browser. No ?

Edit : your iOs version is too old

Requirements#

The server can run on all platforms supported by Electron. Systems that can run Node.js may also be able to run it in headless mode (see Running with Node).

The client is compatible with the following browsers:

  • Firefox: version 75
  • Chromium / Chrome: version 60

iOS devices must be of version 10.3 or higher.
