[Bug]: Unable to confirm Send transaction from the Tokens tab, 'Continue' button is inactive

[sleepytanya]

Describe the bug

If Send transaction started from the Tokens tab, token balance displayed correctly, quotes are fetched but Continue button stays inactive and tx can't be submitted.

Some tokens doesn't have balance shown (screenshots below).

Build 11.14.4 (I don't put it in the 'build' field so 11.14.0 regression label doesn't apply automatically)

Expected behavior

I'm unable to reproduce the above. I wonder if a part of the problem is the account's api not having processed an account or tokens at times.
