+Squads v3 only accepts legacy transactions. If your multisig is on Squads v3, add `--tx-version legacy` so the exported transaction is a legacy transaction instead of a version 0 transaction:
+
+```bash
+npx @solana-program/program-metadata@latest write idl <program-address> --buffer <buffer-address> --export <multisig-address> --export-encoding base58 --close-buffer <your-address-to-get-the-buffer-rent-back> --tx-version legacy
+```
+
 4. Sign the transaction in your multisig and send it
