Common Crossposting Issues and Solutions

We break down common crossposting issues and explain how to fix them. Most limitations are related to platform restrictions.

Features

Signature exceeds media caption limit

Telegram limits photo/video captions to 1024 characters — the sum of post text and signature. If the text is long, the signature won't be added. Use short signatures of 100-150 characters.

Signature not added to forwarded posts

Telegram does not allow bots to edit forwarded messages. If a post is forwarded from another channel, the bot cannot add a signature to it.

Post not published to VK

Check if your VK token has expired (valid for 180 days). Go to the 'VK Channels' section and reconnect your account if needed.

Video not publishing to VK

VK limits video size to 256 MB. If the Telegram video exceeds this limit, publishing is not possible. You can set 'Text only' for large videos in content settings.

FAQ

Why doesn't the signature appear on all posts?

Two main reasons: 1) Telegram limits media captions to 1024 characters (text + signature). If the total exceeds this, the signature won't be added. 2) Forwarded messages cannot be edited — the bot cannot add a signature to them. These are Telegram's own limitations.

Can the 1024 character caption limit be bypassed?

No, this is a hard Telegram Bot API limitation. Even Premium bot accounts don't support extended limits (up to 4096 characters for users). We recommend using short signatures.

Why is a post waiting for a decision?

If 'Ask' is selected in content settings for a certain content type (buttons, large video, polls), the bot sends a notification with action options. You have 1 hour to decide. Check your DMs from @crosslybot.

The bot stopped publishing posts, what should I do?

Check: 1) The bot is an admin of the channel. 2) The project is active (not paused). 3) Monthly post limit is not exhausted. 4) VK token hasn't expired (for VK targets). 5) No errors in the project's 'Posts' section.

Text formatting is lost during crossposting?

Crosslybot supports bold, italic, underline, strikethrough text and links. Spoilers and quotes are automatically removed for VK and Max, as these platforms don't support them.
