MYTVOnline generations organize source settings differently. First read the actual application version, then use the corresponding menu route.
A source can be a portal-style connection, an API login or an M3U playlist under the player’s supported options. The menu location does not decide which method your service issued.

Identify the installed generation
Read the app’s name and version on the device. Do not infer it from a Formuler logo or a product photo. Formuler’s current documentation distinguishes MYTVOnline 2, 3 and 4 rather than presenting one universal screenshot.
Hardware and software support can be model-specific. A guide showing MYTVOnline 4 is not evidence that an older device can install it or that a major upgrade is included.
Use the versioned source route
Formuler’s July 2026 setup guide places version 2 under Menu → Connections, version 3 under Menu → Content Manager → Content Sources, and version 4 under Menu → Settings → App Settings → Content Sources. Read the actual screen before editing.
Preserve the working source configuration privately. A label change, a refresh and a credential edit are different actions. Select the source you intend to manage, especially when several entries have similar names.
Use the actual issued method in its supported fields. Do not paste an M3U URL into a portal field or assume a registered identifier replaces a username/password account.
Check the intended change
After a supported edit, record whether the source loads, fails authentication or returns a specific error. A menu being reachable is only a navigation result. It does not prove that the provider permits the account method or that every feature is available.
If the expected route is absent, report the app generation, model and visible menu to Formuler. Avoid resetting the device merely to match another version’s screenshot. IPTV USA account execution and model compatibility remain separate unverified questions.
Useful answers
Does a version 4 guide mean my older Formuler can upgrade to it?
No. Check the exact model’s supported software; a menu example is not an upgrade entitlement.
Are the version 2 and version 4 source menus identical?
No. Formuler’s current guide provides separate routes for those generations.
