There are some digital libraries that DOI doesn't redirect to the full text version of the paper

As far as we know, MPDI, ACM and Imrpress does not redirect to the full paper version (sometimes). There are some examples in the following documents to test the possible solution to this issue:

• Imrmpress: https://doi.org/10.52586/5066 should be redirected to the https://www.imrpress.com/journal/FBL/26/12/10.52586/5066/htm instead of https://www.imrpress.com/journal/FBL/26/12/10.52586/5066
• MDPI: https://doi.org/10.3390/jcdd9080235 should be redirected to https://www.mdpi.com/2308-3425/9/8/235/htm instead of https://www.mdpi.com/2308-3425/9/8/235
