Question 1

Nothing arrives in my group or channel

Accepted Answer

The bot isn't an admin of the chat, lost its rights, or can't post messages. The rule then shows a delivery error in the mini app. Add the bot as an admin with the right to post messages, then open the rule again after the next post to check that the error is gone.

Question 2

One rule stopped sending anything

Accepted Answer

The rule (or My messages) is switched off, or the source isn't in the rule's list of sources. In Forwarding, check that the rule is on and open it to see which sources it includes.

Question 3

Only some posts arrive

Accepted Answer

The rule has keywords to keep, so only posts with one of them pass, or a word to skip drops the others. Open the rule's filters and remove or add keywords. Without keywords to keep, every post passes.

Question 4

Photos, videos or files don't come through

Accepted Answer

That post type is switched off in “What to forward”, or the file is larger than your plan allows (100 MB, 500 MB or 2 GB). For files that are too big the bot sends you a message. Switch the type back on, or upgrade for larger files.

Question 5

Posts the channel forwarded from others are missing

Accepted Answer

“Skip reposts” is on, so only posts the channel writes itself are sent. Turn “Skip reposts” off in “What to forward”.

Question 6

Forwarding stopped after many posts today

Accepted Answer

The free plan forwards up to 3,000 posts a day. The bot tells you when the limit is reached. Forwarding continues the next day. Premium and Elite have no daily limit.

Question 7

A post disappeared after I added a replacement

Accepted Answer

Your replacements removed all of its text. A text post with nothing left is not sent; a photo or video arrives without the removed caption. Paste the post into “Try it on a post” and make the pattern or removed line narrower.

Question 8

My pattern changes nothing

Accepted Answer

The pattern was typed but not added with +, or it doesn't match the text as the post shows it. Patterns change text, not formatting, so a quote stays a quote unless all its text is removed. Check the preview with a real post, tap + and save the rule. The regex guide has ready-made recipes.

Question 9

A private channel says it needs admin approval

Accepted Answer

The invite link has “Request admin approval” on, so our account sent a join request that waits for the channel's admins. Ask an admin to approve the request in the channel's join requests, then add the same link again. Or use an invite link without approval.

Question 10

I can't add a private channel

Accepted Answer

Private channels need Premium (1 channel) or Elite (5 channels). When your plan ends, private channels pause. Upgrade, or remove a private channel you no longer need to free a slot.

Question 11

Some settings stopped working after a month

Accepted Answer

Plans renew from your Telegram Stars balance. If the balance was too low, the plan wasn't renewed and the account is back on the free plan; settings above its limits pause. Top up Stars and subscribe again in the bot. Your rules and settings are kept and work again right away.

Question 12

Posts arrive in the group's main chat instead of the topic

Accepted Answer

The topic was closed or deleted. Posts then go to the main chat, and the bot tells the rule's owner once. Reopen the topic, or pick another one in the rule.

Question 13

Posts aren't sent to the channel they come from

Accepted Answer

A rule whose destination is also one of its sources would forward its own posts in a loop, so Aggregaat never sends a post back into the channel it came from. Remove that channel from the rule's sources, or forward to a different chat.
