Slow Alex Bridge speed

Bridging from USDT from sepolia to stacks is very slow. Check the picture attached. It’s been processing for 4 minutes now and still pending. Previous ones were so slow that I thought my funds were missing until I checked again and saw that it bridged. Bridging speed should be improved because now it takes more than 20 minutes to bridge.
