Deep link to bot with start parameter shows start button every time

[php4fan]

Steps to reproduce

1. Click on a deep-link to a bot with a start parameter, such as (this is a real link that you can use to test the issue): https://t.me/fume_bot?start=123 (paste this e.g. into your saved messages so you can click it from there)
2. This opens a private chat with the bot, with a "START" button, so click the "START" button
3. Now go back and click on the initial link again

Expected behaviour

This time, this should immediately send the start message to the bot with the (unfortunately hidden, but that's a separate issue in both Desktop and app, probably by wrong design) parameter, to which the bot will immediately respond. That is, this second interaction shouldn't show the "START" button again and require to click it. This is how the mobile Telegram app behaves, and there's no reason for the Desktop application to behave differently

Actual behaviour

No matter how many times you have already talked to the bot and/or sent it a /start command, every single time you click on the deep-link, it will display the START button and you'll need to click it in order for the /start command to be sent. This is inconsistent with the mobile app behavior.

One may argue on which of the two behaviors is better. I personally think the mobile behavior makes much more sense. Either way, the two should have the same behavior.

Relevant, the same issue in Telegram Desktop 4.14.13 x64 on Windows 10. Are there any ways to work around this strange behavior? I need it to behave the same way as in the mobile application, with an instant response when clicking the link.

Same issue: Deep-Link open must NOT require manual press of "start" button from user.

Steps to reproduce

1. find any bot added to your contact-list. As example this will be "mySuperBot"
2. create DeepLink - sth like: t.me/mySuperBot?start=sayHello
3. send this link to your "saved messages"
4. try to click on it

Expected behaviour

DeepLink was opened and no extra action from user is required

Such expected behaviour we can see on:

• "Telegram" for MacOS
• Web Telegram
• iOS telegram
• Android telegram

Actual behaviour

Telegram require extra action from user: manually click "Start" button in the bottom of the window

Operating system / Version of Telegram Desktop

• 5.1.7(Telegram Light MacOS from AppStore)
• 5.2.2 (Windows, static binary from offsite)

---

I believe that this is a CRITICAL BUG

• Buttons / InlineButtons have too many limitations and ARE NOT ENOUGH contextual controls.
• WebApps have a pop-up "your data may be stolen" that scares away a large percentage of users.

And the last convenient tool I know - deep-links - does not work properly on large amount of devices (and only on desktop devices!). I'm not asking to change the button system or remove popups from WebApps.

JUST FIX THIS BUG, PLEASE!!!!

isn't it documented expected behaviour

Start parameter, up to 64 base64url characters: if provided and the bot_username is indeed a bot, the text input bar should be replaced with a Start button (even if the user has already started the bot) that should invoke messages.startBot with the appropriate parameter once clicked. Note that if the bot_username is equal to the premium_bot_username configuration value », clicking on this link should immediately invoke messages.startBot with the appropriate parameter.

If I correctly understand this text:
I need to buy username for my bot on fragment and deeplinks will work without pressing "Start" button.

and buy username for bot have 1000Ton fee.

Absolutely insane politic of Telegram.

@ukushu nope, that "Note" is about a specific, single bot, used to sell premium subscriptions to users.

Same issue here, expected behavior is for the start parameter to run automatically without having to press Start once user has interacted with the bot previously, which is not happening
