Try what I mentioned already. Emulate pressing "enter" button at the end
of "type text" action. Disable "wait full page load" in load action and experiment
with "sleep" or "wait for url loaded" and "wait for addres bar" waiters afterwards.
You can even combine all these actions, so the one that works for given
fingerprint would eventually be executed.
On the other hand, all these problems might be related with BAS browser
engine, which is not updated for long time. There is a statement on forum
that next major update will happen by the end of this month (february 2021)
