It so happened that I used Trezor address (Taproot) to receive lots and lots of tiny (almost dust) transactions which I now want to consolidate. The issue is that for whatever reason the Suite would only submit tx with under ~1800 inputs. If I do more - it would still do the initiation and signing (veryyy slooow) but will fail when finally sending the signed tx with error “-26: tx-size”. If I do under 1800 - it would succeed. Interestingly, it would initiate and sign even 4k inputs, but again very slow, and fail when submitting.
I checked that the successful ~1800 inputs tx has size ~185kb and virtual size ~100kb. I know there is a node-level limitation of 400kb for mempool-eligible tx. So why wouldn’t it allow to submit a bigger tx but under 400kb? Currently I’m consolidating by ~1800 inputs and its painfully slow (like 10 minutes per tx). I even tried the newest Safe 5 which I hoped would sign faster but its about the same speed as Model T… Model One wouldn’t even sign 
So my two pain points are:
- 1800 inputs tx limit
- slow signing
Suggestions?
